My last period was may 16th it was heavier and lasted longer than normal then in June I never had a period at all then in July about a week after I was supposed to get my period I had light spotting(only when I wiped) but it only lasted for a few hours then completely stopped I have been experiencing nausea dizziness gas enlarged breasts and I have noticed veins are very visible and also bloatingto the point where my clothes are a lot more snug than they used to be I have done a test a 5 days ago and it said negative so not sure what to think could I be pregnant but if I am how come it doesn't show up on the test Any advice/experiences would be appreciated
