I am currently taking Chelsea-35 ED birth control pill, and for the first time I decided to miss my period. I did this by missing the placebo tablets and continuing with the active pills, however on the day of my due period and continuing for a few days after I have experienced light brown discharge, some thick and some thin, all light to dark brown. I'm worried because last week my boyfriend and I did grind for a while (no penetration) however tried penetration (possibly an inch in) before recoiling due to uncomfort, all without a condom. I always take my pill at night but the timing can differ by a few hours. I'm just concerned whether this brown discharge is (from what I've read) due to fertilisation or what I really hope to be a result of missing my period for the first time on birth control. Any help please!
