I had my last shot in June 2019 so its been 7 mo total and 4 since it wore off ( I only had two). Had a period around Thanksgiving and now on CD 69 with no ov yet. My BBTs are erratic but not really severe. I have been using the Femometer Ivy LH reader that gives me not only a L,H,P reading, but gives me an actual LH number reading. I got this yesterday but it inly lasted 6-10 hours and then back down to low levels. My BBT was high the lasy few days and was back down yesterday and today. Not sure why it would suddenly fluctuate like this?
