41 years old...and 6 weeks pregnant

I realized yesterday that my period was 8 days late so while I was running errands, I grabbed a pregnancy test. Low and behold, it was positive. I was skeptical because I have struggled with fertility for years due to polycystic ovarian syndrome and diabetes. I went through 3 rounds of Clomid with no success. Then, back in October, I started a diet and exercise program. Once the pounds started falling off, I began to have regular periods. At the beginning of this year, I filed for divorce and shortly thereafter I met an amazing man...obviously we were not careful.  I've taken 3 tests and they're all positive. I am shocked and terrified at this point. I have an appointment tomorrow morning with my OB/GYN.  Wish me luck!
