My boyfriend and I had sex with a condom on June 11th, and I noticed some very light red blood the 15th, and then it was dark brown on the 16th. Very light. It felt like regular discharge, and by the end of the day it was gone. I had also been experiencing some cramping, it wasn't anything severe though. I stopped my period the 6th, and had bits of brown spotting which is normal for me until about the 8th. I was afraid this could be implantation bleeding, but we had protected sex so I just figured it could have just been ovulation spotting or cramping. My period is whacky sometimes, I don't really start on time. But for the most part, I'm usually a week or so late. Yesterday, the 11th, I had some cramping and stomach pain, and bleeding that seemed normal for the start of my period. Last night I took my tampon out and maybe one side of it had blood. I went to the bathroom this morning and had no bleeding, but later on I wiped and it was light brown. Now I just have lower abdominal pain and light cramping, if any. Does anyone know what could be going on? I'm really worried.
