If I had sex with someone April 22nd and I have a period 8 days later normal regular period can the PRE CUM from April 22nd have impregnated me before my period during or after ?

I had sex with another guy may 19th and it says I conceived in May I’m due in February everything matches up to May guy I just want to know if I’m overreacting about April guy. Help...

so is it April guy or May guys baby?
