Friends I read that ovulation predictor kits can pick up hcg and tell you if you are pregnant. I am 4 days late for AF but all pregnancy tests say negative. I used an ovulation test and both lines showed up in equal color. Could I be pregnant? Could I be ovulating when I am supposed to be having Aunt Flo? I am so confused. I also feel pregnant and have been having some symptoms but they could also be PMS symptoms. Any input would be great!
