stress due to hoping you're not pregnant

Emma
I get so stressed every month near the time when I'm supposed to get my period. They're super irregular to begin with, and I tried the pill but it didn't work and my gyno isn't a very nice lady so i need to find someone else to perscribe something different. I get nauseous around my period and that makes me worry that I'm pregnant.
My bf and I use condoms every time but I still stress so much and I hate it. Wondered if other people have similar experiences. And how you manage the stress.
