All the clues were there - I just didn't realise it!!

I was in Amsterdam - didn't know it at the time but was 8 weeks!! I was tired - partner thought I was being miserable by not wanting to walk around sight-seeing. I also went off alcohol - which is very unlike me as I can normally drink the lads under the able - had to get my partner to finish my drinks!! I had tender breasts and my clothes (including my comfy jeans) had gotten a little tight but I just thought I'd put a little weight on and my breasts were sore because my period was due. Got home, had some spotting the next day, which I thought was my period (which was now around 4 days late), did a pregnancy test the day after that and it was positive. I then did a further four tests as I couldn't quite believe the results!! My little boy is now 15months!
