Implantation cramps?

My husband and I had a miscarriage earlier this year via complete molar pregnancy. It was our first pregnancy and we were blessed enough to get pregnant the first month of trying. Fast forward to now and we have been cleared by the doctor to start TTC again. All my life I’ve had a super predictable period. To the extent that in high school I could be like “I know I’m going to start my period by 10am in English class”. I’ve been very lucky in the way of having such a “standard” cycle. Anyways, this week is my most fertile week and I’m most likely ovulating Saturday. My husband and I have been having sex once every two days starting last Thursday the 5th (fertile week according to Glow is the 10th through 16th).

Today I started noticing some uterine cramps. It’s a really specific feeling that I can’t explain. It’s not severe by any means. I just was wondering if there was any chance it could have something to do with implantation? I’m sorry if this is a stupid question.
