I keep feel like my period is about to start but I'm due in 12 days.

I'm having these weird twinges and slight cramps and that soreness that I usually feel when my period is close but I only experience these symptoms 3 days or so before my period actually starts. I just ovulated about 5 days ago cause I felt my ovulation cramps (as usual) and I'm not having and "rough" sex. I have absolutely no idea what going on and I keep looking for signs that I may be pregnant (my mood is all over the place and constantly irritated)

I'm wondering of this is just all in my head and all the signs are just normal PMS or if im actually getting that rainbow baby that I've been dreaming of
