Last 5 days I’ve had one and off pains, around my belly button and towards my uterus sometimes pretty bad pains like my period is coming, but it never showed up.. today I woke up and my nipples are pretty sore, mainly just my left one though, I did take a test 3 days ago but was a pretty clear negative, could’ve it been to early to test? I’m unsure when I’m due for my period because it is irregular but me and my partner have been trying for a baby for over a year now and I’m experiencing some symptoms but no period
