I'm on Vestura and have been for 4 years. My last period started May 28-29 and then I had intercourse around June 6. Yesterday (June 22) I wiped and saw brown bloody discharge, it was kind of a lot so I put in a tampon. This morning, I took it out and there was more brown discharge on it, and what looked like a clot but it may have been caused by blood drying on the tampon. I also have mild cramping. I'm nervous because I'm not supposed to get my period until June 25-26. I know implantation bleeding can happen right before you're supposed to get your period. In the four years I've been on birth control, I've had very regular periods and it has never come early. Does this sound like implantation bleeding?
