Cramping at 7w2d... help!

Hi ladies!! I could use some reassurance. Yesterday, I had my first ultrasound (transvaginal). Dr cleared us for sex at my appt, so last night hubby and I DTD for the first time in a month. After sex, I had some dried blood and pink discharge that completely resolved by the time I went to bed. My major concern is the throbbing I felt in my uterus. It covered my lower abdomen and radiated to my hip flexors and down my legs. It feels 10x better today but is still there. I understand when you orgasm, it causes the uterus to contract.

I have already reached out and left a message with my provider, I’d just like some success stories/ reassurance.

I’ve had one miscarriage before at 5w6d and am paranoid about having another!!

Anyone have this happen and go on to have a successful pregnancy??
