Has anyone had strong pregnancy symptoms from as early as like 5/6 DPO?

We weren’t trying but had unprotected sex on CD11 - I usually ovulate on CD14 and have a normal 28 day cycle but on CD11 I did appear to have fertile CM...didn’t have any opks though so took the chance 🙈

Anyway, since about 5/6 days later I’ve been VERY bloated, frequently urinating and have a dull but very noticeable ache pretty much at my ovaries. It feels completely different to period pains though. I’m not due my period until another week away yet. This would be baby no #2. I just don’t know what these aches could be 🤔 I actually thought I had a UTI because im peeing so much but I had my urine checked and it’s not that
