Basically had sex on the 13th of may. I got my period on the 6th of may it ended on the 11th of may. My fertile days are 19th of may to the 24th of may. My ovulation occurs the 22nd-23rd of may. It was my 2nd time having sex with this man and I lost my virginity to him. We had sex for 25 to 30 minutes and had 3 condoms and we switched condoms every 5-10 minutes, there were no holes in them and he finished in the condom. I think I'm paranoid but yeah. I just want an opinion off someone who knows more about this sort of thing.
