Ovulating and cycle days....

Ok I had a m/c back in Feb of this year. I then got AF on the 4th of March, so that was 29 days from Feb-March. Then 32 days from March-Apri. Ok then 29 days again from April-May. Got AF again on the 2nd of May, and if my cycle is 29 days again this month , AF SHOULD come on the May 30th. So my ? is should I start counting from the first day of my last . if it comes on the 30th of this month??? does that make sense? if so should I be ovulating starting on the 15th day??


Sorry so long it's hard to explain
btw: when i got pg last time my cycle was 29 days


Thanks

Re: Ovulating and cycle days....

If your cycles are typically 29 days, assuming you have an average length luteal phase (14 days) that means that you would ovulate on day 15 of your cycle or the 17th of May. However your LP can vary anywhere from 10-18 days, so really you could ovulate anywhere from cycle day 11 thru cylce day 19, or the 13th thru the 21st of May. Hope this helps.
