I don’t know who is the father of my unborn baby

[Favour34]

I was told by my previous doctor at 13 weeks that my baby is measuring 4day behind, lmp was 20 may, slept with my boyfriend 30 may 3,4,5 June. Also slept with my ex 9 June. My period are irregular. My current doctor said I’m probably 3, 4, or 5days behind at 20weeks now I’m 26weeks and she said same thing she’s not being specific about the day’s I’m really stressed please I need answers.

Do you have any more specific information than the phrase "x days behind"? Because that doesn't help a lot. If you had a crown-to-rump measurement from an ultrasound done at about your 7th week, you might be able to try to guess. But unfortunately now it's too late even to try to tell from an ultrasound, because babies can grow at different rates.

While your boyfriend sounds like he was in the right time frame and your ex a little too late, with your irregular cycles and the sex with the ex being pretty close, you'll need to do a DNA test to be sure. What is your relationship with the two men? Does your boyfriend know there is a question?

(I ask because it is smartest to do a DNA test with both men. One's 'yes' provides confirmation of the other's 'no.')
