HELP- don't know if I'm pregnant😬

Me and my boyfriend always have unprotected sex but he just pulls out, but the past couple times he's said after 'ohhh that was so close!!!' And he's been unsure. Anyway I had a misscaridgee in February and since then my periods have been supper painful because of what happened I think. Recently I have been getting tired from doing basically nothing, had awful headaches, having sore boobs, sore nipples, need a wee more frequently and getting really light headed and dizzy when I stand up. I don't l is if it's too early to do a pregnancy test or if these symptoms could mean anything else. Oh I also feel like I've put on weight and the other day I cried about getting a McDonald's, which is so not like me! If anyone has any ideas what could be going on I would much appreciate it.... thank you in advanced! Xxx
