I am taking progestrone, but I still worry about it. My periods have always been stubborn and would come at odd times even when I was taking BC pills. To top it off, while on BC pills, I managed to get PG two times, but I lost both of them. It is interesting how the body does whatever it wants.
As far as getting sick, it was awful

! I rarely get nausea or upset stomach so it ruined the whole day. However, with my two previous full term pregnancies, I did not get sick at all

. In fact, I was energetic and happy. Every pregnancy is different and you need to remember, you are older now. I was 18 when Danny was born and 21 when Christian was born. Seven years may not seem like a long time, but to your body it is. Not to mention, my RE told us I am premenopausal and will likely stop ovulating within the next 5 years if not sooner. So reproductive time is almost over! It is kind of odd that we chose to have a baby now, because the RE said if we had waited another 6 mths to a year longer, we likely would have had to use donor eggs.
Good Luck Cowgirlclass, you will have your u/s before me! I have to wait until Thursday because my DH is out of town

until then!
