TTC for 3 years

So I had my period on November 3rd- 8th. I don’t know when I’m ovulating because my period is very irregular. But the pass couple of days I’ve been having cramps, headache, sore breast, nausea, but I’m mostly feeling more stomachache and more gassy. The stomach and gassy is a new thing for me because I don’t have them before my period which is not normal for me before I have my period. So I’m really hoping we are actually pregnant and that’s what’s causing the stomachaches and super gassy. Anyways baby dust to all beautiful ladies.
