I have had un-protective sex on the 10th, 12th and 13th but my boyfriend pulled out each time before he could have a chance of leaving anything in me.

My period is due on 16th or 17th. Today the 16th, I have experienced a sort of light brown discharge and a few spotting (but no massive blood flow yet) with a lower backache pain which this sort of pain is normal for when I'll be getting my period. No other symptoms I have experienced yet like headaches or nausea or sore breasts or the need to pee often.

My cycle is 28 days, I've checked the days I am fertile or not. But it leaves me wondering if there would still be a chance where I could still get pregnant.

Could this mean I am pregnant? Also could pre- actually get someone pregnant?

Hello,

If you were due to get your periods on the 16/17th and have a regular 28 day cycle, your last menstrual period would have been on the 18-20th of May and your ovulation dates would have been around the 2nd of this month. Since an ovum remains fertilizable only for about 24-48 hours after ovulation, having sex on the 10th,12th and 13th makes it a little unlikely that you could be pregnant.

That said, sometimes ovulation can be delayed and irregular. You could be pregnant and the bleeding that you have now could be implantation bleeding. Please get a pregnancy test done. If it is negative and you do not get a proper menstrual period within the next week, please repeat the test.

I hope this helps.

implantation bleeding. You have to agree that "implantation bleeding" is not scientifically proven, correct?
