I'm late

So a month ago I had sex with a guy and we used 4 condoms (like not together but one at a time and he only came in one but not inside of me) I'm not too smart on these things so this is why I'm asking. I havent had any pregnancy feeling but I know some women dont get the symptoms. Is there any DIY ways to know if I'm pregnant or any DIY ways to miscarry if that? I'm just lost and unoriented, any help would do
