So..These are my ovulation tests..The one before the faintest one was even fainter..then I got my LH surge did the sexy time took another ovulation test the morning after and there's only one line so negative..what does this mean?? It's only been like 12 hours since I got the LH surge so I thought an ovulation test would either be a stronger line or a fainter one? Help!
