Anyone else experience these symptoms during pregnancy?

I’m 5 DPO, and I’ve had HORRIBLE cramps the passed day and a half. So bad to the point I gave in and took medicine. It feels like this bubble, pulling feeling on the bottom of my uterus and right side. On top of that, this is really weird but my nipples have been SO sore, and to add onto that I’ve had like almost pressure on my vagina the passed 2-3 days, but today has been the worst. I don’t have a UTI, I’m 9 days from my period, and the only time I had sex this cycle was the day before and of my ovulation. Could this be a sign? Or is it still ovulation cramping. I woke up a day ago to brown spotting in my underwear but i believe it’s too soon. Just really stressing out and if it’s a good sign im pregnant I’d like to know so I don’t drink or hurt anything.
