Ladies, I’m fairly new to this app and checking for my LH levels, I use clear blue digital advance in the morning to test. According to this app I was supposed to ovulate on the 9th but, I’m still having high readings. The high readings started on 7th. My partner isn’t close so we was only able to BD on that one day so far. Is it normal to still have a high reading after what was supposed to be ovulation day? Or have I possibly not ovulated this cycle cause I still haven’t had a peak reading either. Any advice is appreciated.
