the babys always measure different on every scan, my babys so far had 5 different due dates, if ur not sure on the daddy the only way to tell is a DNA when babys born. sorry its tough one but it the only way to tell
Wow, that's tough. Is there some reason the father doesn't believe you? Were you with someone else after him? If not, he needs to take responsibility and trust you more. If so, the only way to tell is a DNA test, as I'm sure you already know.
