@nicoanstic_ I completely understand this anxiety. I also suffered from this for YEARS. It was worse when I was younger as well, so maybe that’s a thing? I am 36 now.
I realized the anxiety was partly in due to the kind of birth control I was taking. I was on Depo Provera and because it caused me to miss periods entirely or spot randomly, I never knew if I could be pregnant or not. I didn’t trust that worked the way I knew it was supposed to and it drove me nuts.
I switched to the ring, and it changed everything. With the ring my period is predictable to the day, and I know I’m getting a period (I use it 3 weeks in, one week out where I menstruate, then it goes back in).
This has helped my anxiety so much. I think age will help too. And being able to talk to your partner about it is also wonderful and healthy.
