Thanks everyone
I haven't been to the Dr, had a really strong feeling to just let it be... my belly has 'popped', so it seems that I am pregnant and the tests didn't pick it up. I am breastfeeding my son, maybe that could have an affect? 14 weeks now...! I have been taking vitamins, and as I'm breastfeeding didn't really need to change anything else, wasn't drinking etc anyway!
