Irregular periods

25 October, 2004

Question:

Thanks so much for a very useful site!

I recently came off the pill.
Month 1 it took 44 days for my period to come. Month 2 it took 36 days, but was very light and all brown, no red blood. Now 18 days later I have a "real" (red) and heavy period again.

So my question is about onot… do you think month 2 was a real period (it did last 6 days continuously)? How do you calculate onot when periods are very irregular like this?


Answer:

If you experienced continuous bleeding, although brown, you count the onot from the onset of bleeding. So your onot for next month would be based on your current period: the Hebrew date, the 30th day (onah beinonit) and an 18 day interval from your current period. In general, count from the most recent period. If you're not sure, feel free to get back to us.
