My period was two weeks late, so I took a home test at 5 days and another at 12 days both said negative. I have all the symptoms vomiting, nausea, light headed, weird cravings, frequent urination and off the wall emotional outbursts. My fiance and I have been trying to conceive for 8 months and I thought we finally had it... but just today after being intimate I noticed bright red blood, I think it's my period, but I'm not sure. My cycle is regular and has never been late... Is this normal and has anyone else went through this?
