ovulation cycle

[lyss820]

Some months, my cycle is 28 days, some up to 31 days.
How do I best know my fertility dates?
We tried (a lot) when the app said it was my fertile time but no luck.
Thanks

I'm doing the same thing about having sex every other day, but also since ur periods are little all over the place try using opks they help to pin point when your ovulating because your period varies sometimes I have to test because mine are like that too...good luck

what you can probably try doing is to have sex every other day before you ovulate and then eveyday when its says that u are fertile and then every other day before you period.  That way you will alway have sperm within you in case u ovulate. Thats what im trying this month.  Lots of baby dust....hope this works for you.
