I had sex 2 days before my ovulation and continued having it through out the week, on my ovulation day I had a clear stretchy mucus coming out, I knew I was ovulating then. The next day I started having a stomach ache and took some pills for it. Not long after that same day I started spotting, very lightly through out the whole day and even the next, until at night time I noticed I started my period, I think ? It's lighter than usual, but I am so confused. Is this normal, or what's happening ?

How do you know you were ovulating that day? Have you been attempting to get pregnant and were keeping a Basal Temp chart the last year... or had medical testing done to establish when you were. Or were you using one of those worthless apps or charts? I had to mention that because apparently most women don't realise those are useless, and that women as a whole are fairly inconsistent as to when in their cycle they ovulate.

It is possible that part of the stretchy mucus you experienced was from the sex act itself. Some women will have some light spotting at the time of ovulation, but it is also possible that the light bleeding is from the recent, frequent sex. It could very well be a mix of all three situations. Obviously now you will have to wait and see what happens when you would expect your next period.

Most women will ovulate about 12-16 days before a period is due... regardless of a 21 day cycle or a 35 day cycle, for example. Some women will ovulate a bit sooner or a bit later as the norm for them, and it can happen that you might have an off ovulation now and then, although usually women are pretty consistent. This is why most women are pretty consistent with their periods.

As smoothy said, using the calendar only gives you a place to start. Watching for the changes in cervical mucus can be helpful, along with temping and charting (BBT: basal body temperature) and ovulation predictor tests. Those are the three more common means of getting an idea of when you are most likely to ovulate.
