So scared!!

Molly
I had a miscarriage in March which was so devastating!! I had my period last month which was cycle day 35 and I didn't know if that's because of me miscarrying because I'm usually around 30-32 day cycle before the miscarriage. I'm a day late on my period as of my app.. Been having some cramping and back pain and some nausea! Also I've been eating like a freaking horse! These were some of the things that happened when I found out I was pregnant. I'm just so scared to go take a test and it be negative and I'm also scared its gonna be a faint positive like it was when I found out I was pregnant!(I also did go to dr and she confirmed the pregnancy)  Did anybody feel this way after a miscarriage?? I don't know if I should just wait it out the next week or so to see if she shows! It's so scary to me!! Thanks ladies for any advice you have!!
