Starting to think this might be it

So I’m 8dpo. Yesterday I had these pinching cramps in my uterus weirdest thing nothing like period cramps. I woke up and I felt different. Like I was in a different body. Now other symptoms are beginning. It’s super early. I have 100 hgc tests from amazon so I’ll probably start testing 12 dpo until period or positive. Newest thing happening is middle of the night pee. I never have to get up to go pee I’m 22 and can easily go the whole night even having a big water at my side of my bed I drink before bed. But no water even tonight and up at 3:45 am to pee 😩 hoping it’s all worth it!
