Yes you could have... if there is a question paternity... you will need a DNA test done after the child's birth to positively establish who it was... there is enough of a margin of error in any other means that it could have happened easily during almost any point of that time frame.

You need to give up ALL alcohol at this point now you know you are pregnant or it will negatively affect your developing baby.

His date is an estimated guess... its impossible to guess to a specific day. Its really impossible to guess to a specific week.

That guess could be off as much as 2 weeks before or after....

The problem is in most cases a week more or less isn't a big deal... but most cases isn't all cases, such as yours.. A dna test is as close to 100% accurate that its considered irrefutable proof in the court of law.

Everything else is basically educated guesses based on development benchmarks and milestones and aren't as precise as say, celestial events are. Resulting in a margin of error for even the best of the best medical professionals.

Since the OP has edited her posts, this thread is now closed.

What I was responding to when the posts were edited:

That's strange spoke to my doctor he said there was no way as would not have been ovulating and has period since. He also said ultra sound would not be that far out now I'm worried!

How does your doctor know when you ovulate? Has he been tracking your cycle for several months to know when you ovulate? Have you? Some women, myself included, have a period-like discharge in early pregnancy.

From what I am learning in researching these types of questions and from our experts in pregnancy, early ultrasounds are fairly accurate. It seems they might be off by a couple of days but the development of the fetus is rather consistent at that stage.
