Will I still ovulate when I'm pregnant?

There will be many symptoms when you just get pregnant, but most of the time you will not have ovulation symptoms and you will not have menstruation during this period. So if female friends find that you have not had your period, don’t worry too much. These are all normal symptoms. You may even find that there are some problems with your liver, which leads to poor liver detoxification.

6. Hear the fetal heartbeat

The fetal heartbeat can be clearly heard with a fetal heart monitor at 12 weeks of pregnancy. From 18th to 20th week of pregnancy, the fetal heartbeat can be heard with a fetal heart monitor, which is about 120 to 160 beats per minute.

7. Feel the movement of the fetus

During the fifth month of pregnancy, you will feel the fetus moving in the uterus, which is called fetal movement.

8. Liver and Gallbladder

There are not many changes in the liver during pregnancy. The liver does not enlarge or increase in blood flow. Although the morphology and size of liver cells change slightly, there is no heterogeneity. Liver function tests showed slight changes; cholesterol, alkaline phosphatase, and total cholesterol increased. The ratio of plasma white, albumin and globulin decreased.

9. Endocrine changes

Anterior pituitary enlargement

The anterior pituitary gland enlarges 1-2 times, and the eosinophils increase and hypertrophy to become so-called pregnancy cells. Sometimes the enlarged pituitary gland can compress the optic chiasm and cause bilateral temporal hemianopsia. After delivery, the pituitary gland shrinks and recovers in about 10 days. For example, hemorrhagic shock during or after delivery can cause ischemic necrosis of the hypertrophic pituitary gland, leading to Sheehan syndrome.

During pregnancy, the anterior pituitary gland secretes increased levels of prolactin (PRL), thyrotropin (TSH), adrenocorticotropic hormone (ACTH), and melanocyte stimulating hormone (MSH). PRL begins to increase from the 7th week of pregnancy, and the PRL value in serum can rise from 10mg/ml in the non-pregnant period to 200mg/ml in full-term pregnancy. PRL promotes breast development and prepares for postpartum breastfeeding.

In breastfeeding women, the blood pressure drops to non-pregnant levels within 80-100 days or longer after delivery. In those who are not breastfeeding, their blood sugar levels drop to non-pregnant levels within 3 weeks after delivery. TSH and ACTH secretion increases but no symptoms. The increased secretion of MSH causes pigmentation on the cheeks, nipples, linea alba, vulva, etc. The secretion of growth hormone (GH) remains unchanged, while the secretion of gonadotropin (FSH, LH) decreases, so the follicles in the ovaries during pregnancy no longer mature and ovulation does not occur. However, there was no change in the production of oxytocin and vasopressin by the posterior pituitary.

During pregnancy, the sweat glands and sebaceous glands function hyperactively, and the skin folds in the armpits and perineum may become inflamed and cause erosions, which are often difficult to cure and will not subside until after delivery.
