Please help!! Advice needed

So I found out I was pregnant about 5 days ago, I’ve been taking tests every day and they seem to be getting a little bit darker each time. I’ve had 4 miscarriages within the past 2 years and I didn’t go to the doctors to figure out what was wrong because I realized I needed a break from ttc, this was an accident and although I’m very happy I’m also so scared I’m going to have another miscarriage. I’m a little over 4 weeks now and most of my pregnancies didn’t even make it this far but I’m still worried, Is there anything a doctor can do at this point to help?

I really just need some advice, and on top of this is really stressed out because I told my mom and now our WHOLE family knows. It’s going to hurt so much if this baby doesn’t make it to full term😪
