in all honesty i think only a scan will reveal how many babies you are having, i was 17 weeks pregnant when i found out, the first scan totally missed one of the babies, it was only when i questioned the dates that my doctor sent me for another scan 2 days later only to reveal yes i was 17 weeks pregnant and not only that there were two babies, well they will be two in june and are beautiful a boy and a girl, my bump never really became obvious untill i was around 20 weeks pregnant, so i wouldnt suggest that the size of your bump is an indicator of the fact there might be more than one little one in there, in my first pregnancy i had a noticable bump at 14 weeks with only one baby, now its baby time again and hopefully there is only one in there, but who knows, ive all of a sudden started to grow a rather large bump, im waiting for a scan next week but the doctor thinks i might this time be around 20 weeks pregnant, its only in the last 5 weeks i have knew i was, and only thought i was around 8 weeks, well here we go again, and its the best thing that can happen, xx:lol:
