aching/mild cramping and scared af

I've had 3 miscarriages in the last 14 months. I'm pregnant again and currently 7+4. I've been having issues the last 3 days opening my bowels so could be to do with that but maybe not. It could also be growing pains but maybe not.

I'm so scared right now, I've had mild cramping/aching on and off all afternoon (it's 9pm UK time) I've not had any spotting at all yet and I still feel very nauseous and my boobs are still super sore. I'm just so scared that this might be the start of another miscarriage. My first 2 (at 7 weeks and 9 weeks gestation) both started with bleeding first and then cramps. my last one (6 weeks gestation) started with painful period cramps and bleeding followed hours later.

I'm just scared, any sort of support would be appreciated right now guys :(
