My husband And I decided to have sex one night and it was the first day of my period on March 17th.  I know now we shouldn't have taken it that early in my cycle but we did take it within one hour of him cumming in me. I had a "period" a few days later and it lasted around four days so I'm assuming it worked, and then he came in me again 😣. We didn't think much of it because I was regularly taking my birth control at the time and I was protected during the placebo pills phase but this happened during the 17-23rd of March and now it's April 23rd and no AF yet. I've had brown discharge that looks like cm with old blood and I've had really tacky, toilet paper discharge. Recently I've had really creamy cm (and lots of it). I have cramps every now and then and all negative pregnancy tests (I've taken like 4 just in the past few weeks).
