Hello, so I found out I’m pregnant and according to my last menstrual cycle I should be 8 weeks one day today. But yesterday I had my first ultrasound and I measured 6 weeks. But I am two weeks off. The baby has a heart and was 115 bpm. I’m really confused and worried. Has this happened to anyone? My day to have conceived would be November 15 but just the dates don’t add up...
