I took an ovulation predictor on the 13th of June and it was positive with a faint second line. My husband and I had intercourse for the next couple of days. I took another ovulation predictor on the 17th, and it was also positive, with a very vibrant line. We had relations for the next 4 days. I took a pregnancy test afterwards, but it read negative. I also went to a hospital and had a quantitative pregnancy test done, and it was also negative. Am I taking the tests too early? I m having signs of pregnancy including sore and swollen breasts, swollen feet, and excessive increase in appetite.
