Im still trying to work out my due date hospital have told me 27 july or 3 august but from last period its 24 july. they say you dont fall pregnant until 2 weeks after your period. i found out i was pregnant 15 nov making me then 14 days pregnant i didnt think a test could tell b4 4 weeks. In a previous pregnancy i did have 2 periods and found i was pregnant at 6 weeks.
