Late

I am 5 days late with my period and I am freaking going nuts! I keep testing and they all keep coming out negative. My boobs are sore but nothing else. I cant tell anymore if i am PG or if I am just late on my period. I havent been stressed out or upset or anything out of the normal range. I have no signs of my period and i really am ready to flip off the walls. I keep thinking what if i have some horrible infection that is blocking the way for it to actually come out and thats why its not showing. All these horrible thoughts keep going through my head now and each day i dont get it or i dont get a positive test the thoughts get eerier.

Whats worse is that I have a GYN appt next friday and if I dont get my period by friday and get it later than then I will have it for my appt. can you say gross? but I cant reschedule it because I already made The husband take the day off so I can go.

Fuck!
