TTC issues

Kinia

Hey. It is very easy for me to get pregnant but for some reason can't keep it. I had 2 miscarriages since we TTC and now I got a faint line on my pregnancy test and my period is late 4 days. I am worried this might happen again. Doctors say nothing wrong with me and that it happens. But I'm still worried as it is rare to happen 2-3 times in a row. I don't want to loose this pregnancy, and can't seem to get any advice from the doctor..
