So I'm at cycle day 36 and kinda freaking out. I've never been this late before. I took two tests earlier this week and both were negative. I swear I've felt cramping and thought for sure on a couple different occasions that I was going to see Aunt Flo. But nothing so far. I bought another test to take tomorrow morning. I also spoke to my OB and they did order a blood test for me so I can go at any time. They told me if i haven't started by next week, then they'll need me to come in so they can do a progesterone withdrawal so I'll restart my cycle.
