10DPO sharp cramps

Is this normal? I was in the shower a bit ago and had some sharp pains. It stopped tho. I got out of the shower and hubby wanted to do some freaky deaky👀 so he gets in and just kinda rams it deep and I start having those sharp pains again, enough to where we have to stop. Now I’m still having the pains a few minutes later. 😖 could it be implantation??? Took a test this morning and a lot of people on here said they see something but I read that HCG doesn’t really develop until after implantation. Which is different for every woman. 🥺
