Hi, I am 41 years old and went in for my annual exam last week. And boy was I blown away. I am pregnant. I have been trying to get pregnant for 10 years now. We had just come to accept that I would not get pregnant. I don't know how far along I am. My cycles are very irregular. I had my second ultra sound today and still no heartbeat visible. We are thinking I am around 6 weeks pregnant, Of course I did not even document my last cycle since I really was not concerned about getting pg, and since I am so irregular it never helped me plan. I have been pregnant once before 14 years ago, and gave birth early and she passed away at 4 month old. I would be incredibly excited if this were a viable pregnancy, but since we are not seeing a heartbeat I don't know. I am getting very stressed about this. When should I see a heartbeat, and at what point do I give up hope?????
