Pregnant

So I just found out I’m pregnant, my boyfriend didn’t want anymore kids and I was under the impression that I couldn’t have kids. I’m a high risk for miscarriage, so it’s still possible that I won’t have this baby. I’m kind of panicking, and my boyfriend is panicking. I’m super scared. I don’t even know how far along I am. My period is about 2 weeks late and I’ve taken 3 tests before today that all came back negative. Every test I’ve taken today has been positive, I booked a dr appointment but the earliest they can get me in is the 15th.
