Hi there i have been trying to get pregnant again recently and went to the hospital tonight to get a answer and was told that i was not pregnant that my level for hcg was at like 0/12 which he said means im not pregnant and there test came up negative and ultrasound showed nothing but i have taken 6 test within 3 days and my peorid is suppose to start wed but my doctor told me to keep an eye for first positive so i could take my progestrone pills to help bc of my reaccuring miscarriages im wondering could i be to early for the hcg test to show anything or ultrasound and why did there show negative but mine all showed positive? also could prenatal vitamins or progestrone pills make a pregnancy test show up positive please help im so confused.
