I’m really lost , I’m starting my 1 <a href="https://glowing.com/glow-fertility-program">ivf</a> this month I should start taking medication and shots and do estradiol and progesterone in 2 nd day of my cycle . The thing that I had a very light spotting this morning then nothing .so don’t know if I should consider today as first day of my cycle or should I wait for a period ???!!!! If someone had had the same issue before need advice.thanks
