Measured a wk behind new DD!9/14

So today I went in for my ultrasound confirmation because two weeks ago when I was supposedly six weeks there was only a yolk sac. Today I measured at seven weeks and one day versus the eight weeks and three days I thought I was but it is because my period Is 30 to 32 days on average and messed my ovulation up but that’s OK! They detected a heartbeat at 140 Bpm. Little blob. So new due date is my husband’s birthday. But since this is a guaranteed C-section they will take the baby between 38 and 39 weeks. 09/14/2021 🥳
