Will I get my period today?! 😐

I'm scheduled to start today, no signs yet. Only cramps, hunger, weight gain, and somewhat ache boobs. I am TTC for 2 months now. I'm 30, trying for my second. I took a pregnancy test last Friday & it was negative. So I guess if I'm 5 days late I'll take another pregnancy test. Has anyone ever got a POSTIVE test after getting a Negative? 🎀
