possibly pregnant?

stefwithanf

My husband and I are TTC, and my period is about 3 days late. Starting Tuesday I've been really gassy (sorry tmi), with dull cramping in my lower abs. I've been waking up with a headache, and yesterday and today I've been nauseous and thrown up. I've taken a Preg test, but it came back negative.. Am I losing my mind? I just want some insight into if I could be showing early pregnancy signs, but still getting a negative test result. Thanks for any help in advance
