I'm 17 and I've just started the 21 day pill birth control tablets. The nurse said to me to start taking it on the first day of my period and after 7 days I would be able to not worry about getting pregnant. It's now been 2 weeks (15 days) since I started the pill and my period is still ongoing. I'm still taking the pill every evening at the same time, however I wondered if this is a problem? I know that at my age my hormones are still figuring everything out and my body needs to take time to get used to the pill, however after I've taken the 21 pills I have a week off where you bleed for that week then you start another 21 cycle. What is going to happen if my period is still ongoing after 21 days? It's very annoying as the whole point of going on the pill for me was to be able to have more sex! ha! The blood isn't even like proper blood anymore either, it's like dry blood and is brown. I'm also not getting any pain. Should I go to the doctors about this or just wait it out?
