I'm 30 days late for my October period and my November one should of started today..nothing.  Ebery once in awhile I feel the urge to throw up but don't actually do it. Nipples are sore off and on. Constipated off and on. And I have the constant urge/pressure to pee (super uncomfortable) it almost feels like a yeast infection but there's no nurning or pain (slightest tingle burn barely detectable when I've pee'd a lot in the span of a small time) and when I do go with the urge after already emptyed my bladder recently it's just the tiniest bit that comes out.  I'm a bit more tired than usual. I've taken three tests over the 30 days and they all have come out negative except for the last one a week ago - faint negative and blotchy ink stains in the positive circle (but I'm thinking I just over pee'd)  today I had cramps as if I was about o get my period had three tiny barely detectable dots of blood when I wiped then nothing again. any ideas?
