Based on my last Period I am 8 weeks pregant but I have a feeling I am less weeks then that maybe 5 weeks I could be wrong. Nothing showed on the Ultra sound and I experienced bleededing yesterday from 11am until about into the early evening with Blood Clots. No white sac came out. Can anyone help me did lose my baby or is he or she not showing or could this be a ectopic pregnancy? I have to wait till Monday to call and make an appointment to get more blood work I want to be hopeful that my baby is just not ready to be seen... my husband and I have tried for over 3 year to conceive.
