Sex without a condom, good or bad???

Beth

I’ve been seeing this man for a week, I’ve been travelling through China for the past year & have flown back home to the UK 🇬🇧 for the next month, on my first day back I went shopping & before I even hit the shops I met this man & we’ve been dating since the past week but on our second date we decided to have sex...without a condom & have been ever since but I came on my period yesterday morning so we haven’t had as much sex but we have done it twice while I’ve been on & he loves it. What are the risks of being pregnant even though he hasn’t come inside me at all ???
