My partner and I thought that I was about 6 weeks about a month ago, but I am already starting to show, and I reckon I am much further along.  Going by your period is a guide only, and is not 100% accurate.  My last was late sept/early oct, which should make me about 3 months along now, but having had 4 already, I feel I am further along.  I guess you are just going to have to wait for that scan to be done.  as do i! lol.

I found this link on implantation for you scroll down to the bit where it says NOTE.  you may be further along than you think.

 

cld be i had last period on 5th september to 9th 5days instead of 7 and my dates say i got caught on 5th i know we didnt coz we dont plus it had been my sons birthday on 2nd so we were sooo tired ive had 2 scans now and they say i got caught preg on 5th plus im bigger than i sld be, aslong as your well you'll be fine alot of women have a period at beginning whilst pregnant im hoping my 20 week scan will clear things up.

I dont know if this helps but your not alone hunni xxx

HHHHmmm I always had break through bleeding with mine(when the egg attaches to what it is supposed to) this would indeed make you a little further along....

Best Wishes
