I had sex with guy 1 april 22nd - he did pull out | 10 days later (may1st) got my regular period . May 19th/20/& all days after had sex with same guy (guy2)

But if i started my period in the beginning of the month how is it possible that i couldve conceived in the ending of the month

June 18- no fetal pole was visible at first appointment EDD given was February 10th .. based on sac measurements. Based on my LMP it would be February 5th.

Help. I do not know much about pregnancy?

I have a feeling its guy 2 i just need opinions ... the only way it can be guy1 is if pre cum (if anything bc he did pull out) can live for 10 days then impregnate me after my period ..???
