Help. I am almost a month late. Negative hpt and blood test still feel pregnant. Has anybody had this happen to them. The last time i was pregnant i found out through ultrasound. I had no clue i was even pregnant and found out early only because my doctor thought i had a cyst and ordered and ultrasound. But thats how i found out about my first baby. Never took hpt or blood b4. Is it possible for some women to not show in blood and urine and still be pregnant?
