So my period was 11/13/2017 (31 day regular cycle bled for 5 days) went in for US at what i thought was 6w6d based on my lmp. They said baby had no heartbeat and said i was 7w4d. Which today being 1/2/18 says I’m 7w2d. Declared I️t a MC but I’m so lost Bc how was i 7w4d on 12/30 when based on my lmp I’m only 7w2d? I have light brown discharge no bleeding nor spotting and full lower stomach pains.... they said i will naturally miscarry but it’s going on 5 days now and my OB doesn’t seem to concern. ( i was seen in the ER and contacted my doctor today with no response after his nurse called to check on me) Anyone been through this.... I’m wrecking my brain as I’m really upset about my baby and confused on the dating.... 😞
