45 days

SSo far I'm at 45 days and no period. Lots of white creamy cm.. my boobs are very swollen/hard feeling and veins everywhere... they hurt so bad and I have so much saliva in my mouth. I had a cold around halloween and it seems like I haven't been able to kick this stuffy nose.... I took 2 tests and week ago both negative. I'm almost 2 weeks late. I've never gone passed a 33 days cycle.
