I know this has been done before but I can't find older threads.
Based on the first day of my last period I am now 13 weeks pregnant. However, because my cycle is slightly longer than average (34 days) my midwife has pushed me back by 2 weeks.
My first scan isn't for another 2 weeks but when I was looking through my diary earlier I thought it would be impossible for me to be 11 weeks as that would mean the week I conceived was the week I found out I was pregnant.
Plus i know exactly which week I conceived and it was 2 weeks after my period.
Morning sickness is still horrific too so that's confused me even further!
Can anyone explain this or is it one of those annoying mysteries of pregnancy?
The pregnancy starts from the day you ovulated, which could be up to 7 days after you had sex (this is how long sperm can survive inside you). The first EDD is an apporximation since the midwife doesn't know your ovulation date, neither you can tell for sure based on the length of your cycle (although the longer the cycle, the later the ovulation day). When you do the first scan you will get a more accurate EDD. Don't forget thta the first week of pregnancy, the week the sperm fertilised the ovary, is week 0! So 1 week pregnant means that you have just completed 1 week of being pregnant.
Bugger we are having the nuchal screening this time round so it's likely going to be too late. I'll give them a call tomorrow to explain and see if they can get us in earlier. I guess they are going off the midwife notes.
