Hey girls. Anyone due on or around Dec. 27th? If so do you know your conception date? I'm so confused about mine. My ultrasounds date him right with my lmp, but the dates the doc and conception calendars give me as the conception date cant be right because i know i didn't have sex those days because i had a kidney infection and was on antibiotics (which is how we think i conceived, meds ruled out the bc). Thanks!
