So, me and my fiancé had sex on 12/26 and He came in me. We wore a condom, But bluntly,
It broke. Today is 1/2 and
I'm experiencing light (pink brown)
Blood and bloating and abdominal cramps. I haven't had a regulat peiord in over 4 years (that's how
Long I've been on depo) I got off
7 months Ago. Could it be implantation bleeding or a period?
