I'll start by telling a little bit about myself. I'm 19, only started having sec this year (one person) protected most of the time. We haven't had sex again since the 3rd of October, since then I've had my normal periods. I did experience spotting two days while my calendar said I was fertile in October, now in November this is my third day of being fertile and I'm spotting again, this time a little bit more. I'm not sure if it's because I'm fertile or if I'm having my period again this month. I'm the past I have experienced two periods a month which my doctor said was completely normal. The spotting blood looks just like it does on my period (it's a bright red) the only reason I'm concerned is because I saw it could be some kind of cancer. I'm not feeling any different, (no headache, nausea, sickness) I'm not having any kind of cramps. Should I be concerned about this? Or is this just my body's way of saying my chances of getting pregnant is very high right now. (This spotting on fertile days only just started last month)
