I’m pregnant for the first time and I was wondering if anyone else is as crazy as me to figure out the exact conception date?? Lol. I’m about 8 weeks and 5 days. When I went for my ultrasound, the tech said i was a week earlier than I thought. Does the length of your cycle change anything even after a sonogram? I failed to mention at my dr apt before the ultrasound that im pretty sure my cycle is like 30 - 32 days. And also how many of you guys had gotten a wrong due date at your first ultrasound and was it pushed further back or closer ????
