Hi! The moment when women start feeling the symptoms of pregnancy is various, depending on each female. The levels of the hormones surely start to grow but they dont do that the same with every woman. It happens for many of the pregnant women to have the first pregnancy signs after a few days after the conception took place. After about seven days after the ovulation, the egg adheres to the uterus so it is very likely for you to experience implantation bleeding. This is usually the first sign telling that a woman is pregnant. However, there are some women who say that they felt they are pregnant the next day after the conceiving. Besides the implantation bleeding, missing the menstrual period is an early and very relevant symptom as most women have a regulated menstrual cycle. The rest of the pregnancy symptoms usually appear after a week or two after the missed period. Although the fetal movement cant be observed sooner than sixteen weeks after the ovulation there are some tests that can detect the pregnancy even after eight days past the conception. Another early signal telling that you are pregnant is the increase of the BBT temperatures which can be observed over a period of 18 days. Cramps usually occur in the early phases of the pregnancy as well due to the fact that the uterus starts to expand to make some room for the baby to grow. In the first trimester of the pregnancy, which is until week twelve, you will experience a wide variety of changes starting with abdominal cramps. Very common are the changes when it comes to your tastes in food and these things can be observed very early during your pregnancy. Having nausea in the morning is another symptom that shows you are pregnant starting with the third week of pregnancy. Besides, you will urinate much often than you did before and your breasts will undergo significant transformations as well. You will mainly have swollen and tender breasts and the nipples will get larger and darker. Besides all these symptoms you will feel many more other things such as headaches and mood swings.
