Pregnant??

Jenny
So I would like to know if you could get pregnant even if you use condoms everytime you have sex? I'm afraid I might be pregnant but I have no idea. The last time I had sex was July 28th and me and my SO used a condom. I was suppose to get my period on the 7th and I have not gotten it yet. But ever since the 28th, I have been feeling sick almost every morning and I also have thrown up a few times in the morning as well. Should I wait to take a pregnancy test another few days or take one asap?! I'm so scared and I have never felt so nauseous and sick before. I need all the information and help I can get!! Please!! 😰😱😳
