Even when I'm off the shot it could take 6 weeks to 12 months for my body reset. With the shot I've had irregular bleeding the entire time. Didn't bleed for a year, then started spotting on and off. Lost track of when my 'period' should be bc I never get one, just spotting for times . Recently missed my first shot ever. The window was July 24 to Aug 10. I had unprotected sex the 10th and he came inside of me. I called the doctor and she just kept saying well if you don't want to get pregnant take plan b, when all this time I thought even tho i didn't get it my body is used to it and it usually takes women along timentonget pregnant. The plan b is making me feel sick, what should I expect ??? Is there a chance I am pregnant even tho I took the plan b less than 24hr after? Will I get a period again ...
