There's a lot going on inside your womb now, yes! A lot. And that tiny little ball corresponds hundreds to thousands of cells that multiplies faster and faster each passing day. And when the tiny ball in your womb “blastocyte” resides in the thick lining of your uterus, then starts the production of HCG hormone (human chorionic gonadotropin). This hormone will make the pregnancy test results to POSITIVE consisting with two lines that tells you “I am pregnant.” It will directly inform the ovaries to stop releasing eggs and activates heighten production of Estrogen as well as Progesterone which stimulates the growth of the placenta and prevents the lining of the uterus from shedding. If you still missed your period about a couple of days and the pregnancy test tells you Negative, then try again for you to know if there is really a human being formed inside your womb.
At 3 weeks, maybe you wont notice that you're a mother now because sometimes, there are no changes yet but in different cases, some women can also be aware that they are ovulating. Some will just ignore the red or pink spots caused by the egg penetrating into the uterine lining and increased discharges. While some will really take a look if they are positively pregnant. At this time, the right choice to know is to weigh yourself at one time to see the difference for you may feel a slight bloating of your abdomen due to ovulation. As time goes by, you will see and find out that your waistline is broadening. Remember ladies, if you knew your a mother now, please be aware of the changes such as weight gain during pregnancy for this is natural.
