I'm 3 days late. i took a hpt and it said neg. my tummy has a heavy feeling, no pms signs or the "usual pregnancy sym". am i just over stressing?

Learn the facts: Knowledge is power! Find good reproduction info - scientific online sites, libraries, women's clinics, pharmacies or your doctor. If you have unprotected sex near the time you ovulate and both of your bodies work well - you will be likely to conceive. Any day has some chance w/o protection. 3 days may be too early, so test again soon or have an exam. Take this seriously. Best wishes!

Maybe : If you are concerned about being pregnant, I suggest you have a blood pregnancy test 1 week after a missed period. A normal cycle can be 21-45 days and last 2-7 days
