Your LMP started on Feb 14?
If so, odds favor it being Guy 1 on Feb 26. Timing wise you'd have been near/at your peak fertility. The pull out method is NOT reliable either.
Normally you'd ovulate between days 11-16 of your cycle (Feb 25-Mar 2). The egg is only viable for up to about 48 hours max. Sperm can survive up to about 5 days - max.
The Mar 4 guy would have very late and the viability of the egg would be decreasing rapidly. It is still possible however.
You'll need a DNA test to confirm.
