weird questions

So a couple of weeks after my miscarriage my SO and I had unprotected sex. He pulled out and cummed a little then put it back in. Can I still get pregnant that way? And my other question is when we have sex and I am on top he pulls out and cums and it hits my vigina. Can I also get pregnant that way? Sorry if these are stupid questions I am new with the whole pregnancy thing. Plus we are trying but not really trying if you get what I mean.
