Possibly pregnant

So since Thursday I have felt nauseous all day. Today I woke up still not feeling I crawled out of bed and barley made it to the restroom before vomiting not much just a little. Despite my better judgement I ate breakfast and drove myself to work only to continue vomiting on and off all day ran to the bathroom at least 20 times only got sick two or three times. I was mostly vomiting water. Period is not due till Sunday according to glow and I have been logging my symptoms and glow says its an abnormal period. I have not been pregnant before so just wondering if this is normal or if it's too soon to have symptoms. Hubby and I baby danced all but one day during my fertile days. I don't want to take a test only to have my hopes and dreams crushed again by a BFN. Any advice would be appreciated
