Pregnant ??

I am very nervous my boyfriend has always been finishing outside me and always ask me you won’t get pregnant right !! But last month he surprised me he said Honey next month (witch is this month September) I am going to finish inside you the whole month we have been having sex multiple times in the morning or when we get home from work to be exact it’s been more than 50 times till today and all this times he’s been finishing inside me , in the beginning of our relationship he had said no more babies he is older than me by 16 year he has 4 girls and a Son , I have 3 girls so it’s was fine with me not having babies even though I always wanted a baby Boy 😊 , I have taken 3 pregnancy test till yesterday and they have been Negative I do feel my body a little bit different but my calendar say 4 more days to my period. And he’s been making comments like are we having a baby or like every time I wanna ask him something he say are you pregnant??

What do you think 🤔 am I pregnant 🤰???
