So here's my situation and I don't know what else to do.

I've posted here a few times but I am posting again. So my last period was May 21st. I didn't get my period in June at all. My periods are irregular and I have a hormone imbalance. I had sex on the 9th and the 10th of July. We used a condom and he didn't cum in me with the condom on he pulled out before he came. I have since tested myself because my period is late. All of the pee tests came back negative, even the one a doctor did for me, except one came back with a weird grey line. I cannot get into a doctor until maybe the end of August, that's when I have a scheduled appointment. My boobs and back hurt and those are my only symptoms besides a missed period but I don't really know when my period is or was due. Could someone please help me out on what I should do? I am confused and lost. My other friends tell me to just wait and stop testing because it's driving me insane.
