I went for another ultra sound today because last Friday they couldn’t see the baby. Today they saw the baby and said it measure 6 weeks four day which is where I should be according to the apps that take into account cycle length. I was thrilled, but then I got to my appointment with my doctor and he told me the heartbeat was concerning bc it was only 93.... now I have to wait another week and hope for the best. Worried now. Anyone else have this happen?TIA
