How long do I wait until I can begin charting ovulation again?

Question

Baby born end of September.
Depo shot received from November to March
Mirena IUD in place from March-2 weeks ago in July.
No real period on either of the above, but had one the day after the IUD came out, for the length that I had them before having my daughter.
How many periods do I need to have before I can start charting again? Ive always been very regular, but wondering if it changed.

Any idea of how accurate an ovulation calculator would be? They used to be right on, verified with charting.

Answer 1

you can start charting now if you know the day you started your last period. If you don't know wait until your next period and start that as day one of your charting. Read the book "Taking Charge of Your Fertility" . It is great and gives you a lot of information on all topics of a womans fertility and helps alot with charting. Good luck

Answer 2

You can start charting now. The calculators may not be correct until you establish a regular period again. They go off a 28 day period. If you use OPK's and chart temperature then you'll be covered.

Answer 3

i would wait til the next period to come, chart that, then wait until the month after to chart for OV because your period woud need to be stable and you would need to know your cycle legnth.
