So according to two different apps (this one and Ovia) I was supposed to start my period yesterday. I have been super regular since I've started tracking it. I think I'm just driving myself crazy but I can't help it! No sign of my period. I did a pregnancy test yesterday and it was negative. However, I was with my sister and we only waited like 30 seconds and tossed it cause we were in the supermarket in a hurry. I was soo bummed 😔 I figured my period would start today but nothing yet. I don't wanna do another test and be disappointed again but waiting is killing me! Any thoughts/advice??
