It is important to listen to the signals your body gave to you in pregnancies. The first trimester is critical for both of you, your baby`s organs are forming so you need to be careful regarding stress.

Nausea & morning sickness

The biggest Don’t is to stop taking medications on your own. You can ask your doctor, it’s their niche, not yours. Stop self-medication as you are connected to another soul, it’s not about you only now. Even if you want to take multivitamins seek your doctor`s help as your body is already going through chemical/hormonal changes don’t feed it with more chemicals on your own.[5]

Can I bend in the first trimester of pregnancy?

Bending can be critical but it is not that you cannot bend. It is better to keep your back posture straight and bend from sideward. Do not bend from the front side or belly directly as this will press the belly. The pain is consistent in pregnancy. All you need is to evaluate the pain. At times you may feel menstruation-like pain in the abdomen which is mainly because your womb is increasing its size. You may also feel pain in your legs and back. If the pain is increased in the lower belly take immediate notice. As intense pain in the lower belly is odd. Consulting a doctor would be loftier.

Why sleeping on the left side is better in the first trimester of pregnancy?

The logic behind this is mainly to provide your body a proper flow of blood. It is ideal to sleep on the sides, not on the back or stomach. The left side is preferred as our larger vein runs in parallel to the spine on the right side. If we sleep on the left side it will allow the body to flow the blood properly. Also, the liver lies on the right side so it is better to avoid pressure on it and let the baby reside on the opposite flank.

Sex in the first trimester of pregnancy

Sex can be nauseous and exhausting to mothers. It cannot clue to miscarriages; it is a mythos. Well, let’s get it logical, the baby inside cannot see anything coming and the Penis is not allowed to enter beyond the natural limits more than a vagina. So it is safe until the doctor advised not to do so. However, some mothers may lose the urge for sex and some feel more aroused. They might not enjoy it all or they might be at the peak of sensations. Later on, it is not recommended as it creates the sensations of mild contractions but in the first trimester, it is not the case. If the water bag is broken or the mother is having any infection beneath or any other transmissible disease is diagnosed in your partner, it is advised not to have sex. Be mindful in sex positions as a bad position may elicit pain in the mother’s body. It is better to have sex from lateral sides or partner behind.

Vaginal bleeding or a spot in the first trimester of pregnancy

Indeed, it is an alarming situation to seek immediate help from your doctor. As it may be a sign of placental dysfunction. It is not necessary every time that bleeding is for abortion, the appearance of color, pain, and level of bleeding differs from situation to situation but it is also not something to be ignored. Some women may face a little spotting still medical assistance is required as this may trigger another issue. [6]

Foods to avoid & Diet plan to follow in the first trimester of pregnancy

In the first trimester, you might not have to deal with extra calories but you need to develop a routine and increase the diet gradually. As ultimately it is about the health of your baby and you. Say no to drugs, smoking, and alcohol. Eliminate the fast food, carbonated drinks, and frozen foods from your diet. Eat-in portions, plan your meals sensibly. As eating more is not a good thing, it will only lead to obesity, eating healthy and moderate is an upright thing. [7]

Portions meal:

At least plan 5 meals portions for your diet plans. Focus on food items that can be digested easily. Make sure the liquid intake is greater than you used to take before pregnancy. Avoid high fat, fried and spicy foods to avoid heartburn and acid refluxes. Keep in mind the essential nutrients i.e., proteins, iron, vitamin C, DHA, calcium, iodine, fats, and folic acid. Add fruits (berries especially), egg yolk, vegetables, and whole grains to fulfill these nutrients. In your meals raise your iron level intake to evade anemia. Eat iron-rich green vegetables like spinach, asparagus, broccoli, kale, lentils, chickpeas, etc. Don’t forget to add the dairy product preferably yogurt as it will be the source of calcium. Beans will add a protein factor to your meals. Whole grains will aid in the proper bowel movements. Whole-grain bread can be a rich source of fiber. Fishes with low-level mercury can be a good source of omega-3 fatty acids. However, be conscious to eat fish (high levels of mercury). Also avoid cheese (especially in pizza), raw cook egg, or poorly cooked meat. On snack time between meals have a fruit it will get you nutrient, fulfill your hunger, and also lessens nausea.[8]

Final thoughts:

Meanwhile, you started taking care of yourself, your partner gets more empathetic towards you. However, keep in mind the symptoms may differ as everybody has their way to respond to the changes in pregnancy. Not everything you read implies on you. The data on the internet is to share ideas and experiences of oneself. So, don’t think too much let the doctors decide for you. Finest you can do being a mother is, be a peaceful and healthy mother.
