Ok, so recently I just started the NuvaRing (it's a form of birth control for those of you who are not familiar with it) and as soon as I stop it, I should get my period and then start it again exactly one week later. Well...tomorrow marks the week I start it up again and auntie flow hasn't come yet (there's no chance I'm pregnant either so I know that's not the case). Has anyone experienced irregularity while using BC, or atleast within the first month of using it? Also, my mom has Poly Cystic Ovary Disease...I know that can be hereditary, but she's the only one in my family with it and for some reasom I didn't think it was really possible to have it with cf (at the moment I have no idea where I got that from). Is there anyone on here with these sorts of problems or with PCOD? I'm planning on calling the doc this week but I'm getting a little worried and still have a bit of the weekend to wait out and figured I'd see if anyone had some input.
