Anxious about first pregnancy after miscarriage, help?

Dulce

Last Friday I found out I’m pregnant with my first baby, I had a miscarriage last year and now I’m anxious it’ll happen again. Right now I am having cramps, kinda painful at times but they never last more than a few seconds, I am also having constant headaches and nausea after eating and in exhausted. I also get randomly dizzy and for a second or two it feels like everything is spinning. I have also been having low back pain behind my hips, the pain alternates between the left and right side. Are these symptoms all common? Everything I’ve read online is really conflicting, it seems like the signs of a good pregnancy are also the signs of horrible things that could happen to me or my baby. I scheduled my appointment but it won’t be for another three weeks since I’m barely about 5 weeks along and because of my last miscarriage I don’t want to ask my mom for advice because I don’t want her to be sad if something was to be wrong. Can someone share any advice? Or their own personal stories? Thank y’all in advance
