Im 20. I was on the nuva ring for a few months. I took it out August 23 2016 and had a period the 26-31. I didn't put a new one in I chose to stay off BC. I haven't had a period since. Its been 3 months and still no period. I've had Brown spotting a few times but no full period. I've had unprotected sex with my boyfriend for the past month very often (everyday) I took a plan B pill on the 8th && 11th but my doctor said due to my weight && BMI it won't work for me. Its been almost a month since we started having unprotected sex but my pregnancy test is negative. Im thinking that its only been a few weeks since I took the plan b that maybe it worked but I also haven't had a period since I've been off the nuva ring so how can I ovulate && get pregnant? Im not sure what's going on but were trynna plan a baby now and not sure how todo that if im not having periods? Please help
