So I am 15 weeks pregnant with my first baby and over the last week I seem to have acquired a huge bump! A colleague at work is 25 weeks and I am sure I am bigger than her - to the point where people stand up for me on the train! And I can only fit on maternity clothes as my tummy is really round. I'm normally a size 12 - 14. Is this normal? I thought I would be more under the radar until after my 20 week scan.
