Hello I?m 22 years girl, the problem is that I have bleeding in the middle of my normal cycle, since the ovulation day, and now it?s the third day ,still I have blood but less, it was at first brown then turned into light red, I took ipill one week ago and, one the last day of my period we did intercourse with my partner but didn?t take any pill, and lately I was really stressed and and also I was sick and took amoxicillin, now I wonder what is this blood? Could it be implantation or ovulation bleeding, will appreciate any help please.
