Thanks for your question! Our Healthcare Expert will be answering some questions every week but in the meantime, here's a little tip from our Careline! During menstruation. your body is already active in preparing you for the next fertile period to get pregnant. Estrogen plays an important role during ovulation. The development of the blood vessels, endometrial secretions and tissue build up in the uterus is a key success to achieve pregnancy. If you become pregnant, the egg moves into your uterus and attaches to the lining and thickens the wall lining. If you are not pregnant, the lining of the uterus is shed through the vaginal opening causing the thin out of the uterus lining. Then, a new menstrual cycle begins. Some of the symptoms you experience during this period might be similar to those during pregnancy. To know if you have successfully conceived, the best is to test with a pregnancy test kit after you missed your menses for about 10 - 14 days or visit your gynae for a blood test if you wish to know the result fast. Do consult your gynae for further advice or if you feel any discomfort.
