Hello, I just wanted to make things clear, I had sex with someone on the 7th Feb, then got back with my current partner on the 14th Feb then at the end of March I fell pregnant I wasn't having periods so wants expecting this, but I'm due the 20th November is there anyway the person I slept with on the 7th could be the father? I'm sure he's not bcoz it's a few weeks difference including the first 2 weeks before conception. Just need to be reasured

Dates are too close to tell. The ONLY surefire method is a DNA test after the birth.

Try pregnancy apps and try to find your conception date from that or else get to know what's the fetus age is when you do next sonogram (not the LMP date). From the fetus age you may count back your conception date.

Pregnancy apps do nothing conclusive. 2 weeks is very close together. You don't know when you 'fell pregnant.' Conception date is ALWAYS a guess unless you had sex only ONCE over a very long period. Even the path of the egg down the fallopian tube and the fertilization by a sperm can vary from minutes to several days. Curlyben was right.

The two men were only 7 days apart... tell both of them because you will only know after the baby is born, As far as apps... they are worthless. Some women can and have gotten pregnant during their period... and others at any point in the cycle. Proof that its impossible to predict based on a calendar (which basically is what an app does) when there is that much variation from one woman to the next.

As was said, the only conclusive test is a DNA test AFTER the birth of your child. Anything else is but speculation, and high hopes.

Sorry, I know you want your boyfriend to be the baby daddy, but it could be the other guy just as easily.

Did you continue to have sex with your current partner after February 14th? With a due date of Nov. 20th, if determined by an early scan, you would have conceived around the end of Feb/early March. Scans are not exact, but they are quite close in the first trimester due to the predictable development of baby. If you want to know with absolute certainty, have a DNA test done as has been suggested.

DNA is the only way.

Your post isn't 100% clear, but based on how I read it you had sex with one potential daddy on the 7th, and the other potential daddy on the 14th? Is that right?

It could be either one. Ultrasounds aren't exact, they have a 2 week window either way, 2 weeks before or after, which adds up to a month. If you do a bit of research on pregnancy and how it works, guy one 7 days earlier and guy two 7 days later, both have a 50/50 chance of being the daddy. Sorry, but that's how it works. Pregnancy doesn't happen on the day you have sex, it takes a while. Both men have an equal shot at being a daddy.

The only way to know for sure who the daddy is, is a DNA test after baby is born. Sadly that's the ONLY way. And no, no matter how much you want to know now, or how much you want to justify picking one instead of the other, there's no way to know until baby is born and a DNA test is done, so save us all from the emotional stuff, this is science, and science doesn't care how you feel.

DNA test after baby is born, that's the ONLY option.

All we can do is wish you good luck and all you can do is hope that the DNA proves that it's the guy you want for the daddy.
