am pregnant with a spontaneous pregnancy after 3 years of IVF to conceive my daughter. We went for an early scan yesterday at what should have been 7+4 based on LMP. The midwife said baby was measuring 6+3 and heart rate was on the slower side at 101bpm. She said it’s 50:50. It’s possible the dates are out and the heart has only just started beating. It’s also possible this won’t be a viable pregnancy. We are going back next week for a follow up scan. I’m terrified. Does any one have any stories from a similar situation? Good or bad, just trying to be realistic about the outcome. Thank you x
