Hunting Down Ovulation with an Irregular Cycle

Taylor
Help! My husband and I have decided to try and start a family. I had been on birth control for 7 years up until 5 months ago, so my period has been weird and irregular ever since. Does anyone have any advice on the best way to track down my ovulating days? I've bought the little tests, but it's annoying taking them every day when I have no clue when my two peak days remotely fall in a month. At this point, I guess we will just have sex every other day to hopefully nab one of the two days!
