Please help! Spotting pregnancy or not?!

flo

My last period was on 23/07 and on 2.08 I had a little spotting… my cicle are regular and I wanna be a mom♥️ I have a lot of cramps on my belly, my ovarian hurting me a little… my boobs are just a little bigger.

My test was negative the next day when I take one. Should to wait more? When can I do a test? I feel cramps in my uterus…
