Just had a transvaginal ultrasound and the tech said no baby. My blood test was also negative. I would be 8 weeks, if I were pregnant. However, she said that my uterus is tilted. Would that make it more difficult to detect pregnancy? Also, my breasts & nipples have enlarged/swollen, my belly button is getting shallower, and I m having salt and beef cravings. Could this be a ycryptic pregnanc?
