just coming off birth control

So long story short, we decided to start ttc so I came off the pill the first of February, then I got my period beginning of March and had a bit of a freak out, and put myself back on the pill. I was on it for the month of March. Then about a week ago I decided to come off the pill again and we had sex on one of my most fertile days (hadn't started tracking again at that time so not totally sure) I still have another week until AF gets here but since yesterday morning I've been lightly spotting brownish-pink but I do have some clumps(?) in the discharge as well. So confused. Any ideas???
