So I’m a little confused, because my cycle has always been pretty regular once a month, with the occasional week extra added on. But for the last couple of months, my cycle has been 60 days long. Like the last two periods I had were both 20-30 days late. Tomorrow should be the last day of my period and I’m not sure how long I should wait before starting to test for ovulation. I don’t want to start too early and end up wasting tests, but I also don’t want to wait too long and miss it!
