How far along does this make me?

Sorry, my head is a mess. I had my last period the last week of August, 25th to 31st and I have a 27 day cycle. I did have some old blood in September but was definitely not a period or new blood and didn't last long. How many weeks would all of this make me? Not been able to get ahold of the maternity unit yet, phone keeps ringing out, I've left a voicemail.

You’re 9 weeks pregnant. You count from the first day of your last period - so from the 25th of August.
They might adjust by a day because your cycle length is 27days. You can use a calculator to work it out - like this mumsnet one.

Yep, 9+3 today. Your cycle length doesn't come in to it at this point. You might get an adjustment of a few days once you get to your first scan.

As others have said, it will be assumed you are 9+3 until you get a scan then that will be confirmed or adjusted.
