(And as to the fact that the guy pulled out, we hear all the time on this site from women who are pregnant and the guy never ejaculated in their body. Pre-ejaculate can contain sperm.)
I guess I'm wondering what the tracker is tracking. If you expected your period to come on the 24th, two weeks back from that is not May 7 but May 10, and especially if your last period came April 26, this suggests your cycles are a regular 28-day cycle. So what data is the tracker tracking that tells it something different? This obviously matters if you want the guy from the 5th to be the dad. The 10th is about the worst possible day in this cluster of sexual encounters for it to be the first guy, his sperm from the 5th might be goners and his sperm from the 11th would not have arrived on the scene yet, leaving only the pulling-out guy as a candidate.
When did your last period begin, April 23?
Why don't you take a pregnancy test? The ones from Dollar Store are surprisingly good and not costly. I probably don't have to tell you that pulling out is ineffective as a method of birth control.
