Just told that I need to start birth control again for PCOS this time and to avoid/lower chances for endometriosis.

For the last month I swear I was pregnant but it’s like now there’s a chance I couldn’t.

Just doesn’t make sense.

It’s weird cause my periods are regular. They haven’t changed. The only thing changed is now I spot before and after period.

Then this month it was 3 days of spotting instead of actual period. I’m just upset now.

Advice for what to do from here??
