I’m so confused!?!!

My boyfriend and I have are trying to having a kid. 9th was my last ovulation day. I’ve been having sore breasts, cramping like crazy (hips, lower back, and vaginal) I’m always crying about something which isn’t normal for me. I’m always tired... everything sounds like it’s leaded up to a early pregnancy symptoms!

I’m 3 days away from having my period. I’ve taken pregnancy tests everyday from 7 DPO... all negative.. most are just dollar tree pregnancy test, but today I took one from clear blue digital and it came out negative... is it still to early, or am I really not pregnant..?
