I have a regular 28 day cycle and today is day 13. I have been taking ovulation test and still no sign of ovulation. Not even the faintest line! I'm so worried I won't ovulate. I just want to cry! My husband seems to think I'm already pregnant but I just don't think so! Does anyone else use first response ovulation test? Will that second line just show up over night? Helpppp!!! Pleeeeasse!!!
