Beyond worried of miscarriage

I had a miscarriage a year ago at around 5 weeks . Today I’m currently 7w5d and I’ll I can do is worry that every single cramp is a miscarriage again. I had bleeding in the earlier week of this pregnancy, but checked for baby and heart beat and it was all there. A perfect 110bpm. But I just can’t seem to worry.

I had a terrible nightmare last night that I caught this stupid virus and when they checked for baby at hospital. It was gone. An empty sac. I just want to be past this part. I just pray so much I don’t loose this baby.

How do I know these cramps are normal or not. I check for blood every time I pee. I’m beyond stressed out.

Please god, don’t take this baby from me. Please
