This is our second month TTC and I decided to try to track my ovulation and I don’t seem to be ovulating! I’ve used the OPK tests and don’t seem to be having an LH surge at all? There is always a line but the test line is always fainter than the control line and never seems to get darker to indicate a positive. My periods are regular and everything seems normal so I’m a bit concerned. Are ovulation tests 100% reliable? Could I be doing something wrong? Picture attached for reference from cycle day 11 but this is now day 13 and todays test looked the same.
