I am due my period in around 6-7 days and I am on day 4 of having nausea. I got some pink mucus like discharge 2 days ago. I keep being able to smell weird perfume/soap like smells that no one else can. I have been super gassy (which isn’t like me at all) and have had a couple of headaches. I took a test last night and it was negative - was it too soon or am I imagining all hear symptoms?
