My period is 2 days late...(from expected period day). I never got a positive while testing for ovulation but stopped testing on day 18...I've taken 3 pregnancy tests since Friday and all were negative. Is it possible I ovulated earlier than day 9 and later than day 18 and am pregnant? Maybe I'm getting my hopes up but is it possible my hcg can't show up in urine? Should I ask for a blood test? I feel no signs of AF coming like I usually do. My hubby is going for semen analysis Thursday and I would hate to waste money if I could be pregnant now. Suggestions???
