so scared.

I'm 5 weeks today and I haven't got to go to my doctor yet and I'm scared that something is going to happen to my baby. I have been having cramps and sharp pains in my lower abdomen since the day before my positive test and my boobs are not sore just my nipples and that's really the only symptoms I've been having. I just don't want to miscarry or have a tubal pregnancy. This is also my first pregnancy.
