Agreed for unprotected and now worried

We have been together for 2 years and having s*x for 1.5 years..4 months back he got a really good job in the other city and would come hardly once a month we would have s*x daily on those days.. I finally agreed to move in with him now that we are engaged.. He said he wanted to have s*x without condom since 2 yrs and also wanted us to get pregnant now.. however I agreed and we did it for 3 4 times in that night.. now after 3days I have this weird feeling of not wanting to get pregnant.. he was touching me today but didnt let him penetrate i just said him im sore down there after that night..

What do I do?
