Is anybody going through this

Alicia

So me and my bf had sex last night, and this morning I had a little blood so I put a tampon in but then we had sex again and there was no blood and I didn’t bleed throughout the day. I’m just curious what’s going on bc for the past month I had a period every other week. I have the implant for a year now but my periods weren’t like this before hand I hardly had a period and now this is going on
