Implantation question

Lulou

Hello everyone. I think I may be pregnant but I am not sure. I am currently 7dpo and I am feeling mild cramps on my left side.

I had a missed-carriage in April followed by a D&C; surgery and since that my cycle has been very different. For example, on my ovulation day, I feel mild period-like cramping and bloating (I never did post surgery) and my periods are shorter but a lot more instance.

I never felt implantation before (I have had a successful pregnancy before) so I am wondering if anyone had ever experienced cramping or mild period pain during implantation.

Thanks
