I'm 18, and 5 days ago I lost my virginity to my boyfriend, and the first time it was protected, but the second time we didn't use protection at all. That night I started feeling nauseous and crampy for a little bit, but I was thinking it was nerves. Fast forward 5 days later and I can barely keep my eyes open in my 8 AM class, I'm extremely tired and exhausted all day, I've had cramps like no other (I'm currently ovulating, but my cramps haven't been as bad as the ones I'm experiencing), I've been really nauseous and have come close to throwing up (I haven't even come remotely close to throwing up in 3 years), I have cold-like symptoms (stuffy nose and sneezing), I've been experiencing some back/shoulder pain, and I've acquired some cravings. Is there any chance these are very, very early pregnancy symptoms? Could I be pregnant? And when is the earliest I can take a pregnancy test? It's only been 5 days since intercourse, but if it's not normal to experience pregnancy symptoms this early, then I have no idea why I'm experiencing these symptoms.
