Concerns; words of advice welcome!

Samantha • 21 in October, pregnant with baby #1. In school working towards a veterinary science degree while working as a veterinary technician at 2 hospitals.

I just found out that I'm pregnant, guessing around 5 or 6 weeks along! Yay! Not what my boyfriend and I were expecting so soon but we've been together for 5 years so I think we can handle it, we're both so excited and so are our families.

But I've always had concerns about being pregnant just because my mom had soo many miscarriages in the past, I was afraid they would genetically pass on to me, I know that isn't how it works but I still get worried. So, I'm trying to keep calm and not think about it but it's difficult. Does anyone have any helpful advice?
