temping is the only sure-fire way to be clear about your ovulation... but for several months i used opks and my fertility monitor, and it was pretty accurate... but im not sure i actually ovulated every month, even with positive opks!
before mirena i had heavy, long periods that were very irregular (35-50+ days). I had DS and had mirena put in at 5 weeks pp... during the time I had it in, my periods were extremely light- as in... I would go to the bathroom, wipe, and there would be a bit of blood... then nothing. that was it! I had removal bleeding 4 days after having it taken out (had it in for 2.5 years)...then my first af 38 days later. since then my periods have been pretty regular at 28-33 days each cycle! I am on my 12th cycle TTC since!
4-5 more days until testing! I started my usual dull pressure/cramps today! boo!
