I've been on methadone for about a year. My periods didn't stop till I went up to 60 and I've got up twice since. I've had one period in 6 months, that's it. I got pregnant once right before my periods stopped totally. The baby didn't make it. So, I freak out when I get sore breast. It feels like maybe period systoms. I really don't think I'm Prego. Hell how can I get pregnant if I have zero periods? Help? Freaking out. Has anyone else ever has their period stop, but still get sore breast? Thanks
