Unprotected sex

So I got my iud out the other day due to much bleeding and my s/o knows I’m letting my body reset before starting the pill. So the first time we had sex he pulled out and I said did you pull out all the way he said kinda and I was like why kinda no response. Then yesterday he’s been wanting to have sex way more often all the time now said very sweet words during it then said I want to get you pregnant not sure if he was kidding around but he hardly ever says things like that but he did pull out that time. Also again last night he started playing with me watching a movie things went from there and he ended up coming inside me he told me he did and said you better go to the bathroom lol. But he’s been so much more loving and by my side more then often I don’t get what’s gotten into him not gonna say it’s a bad thing but what are you’re thoughts?
