My last period was February 19th of this year. It is now 2 weeks late but I've been having cramps and really tender breasts. For the past week, I've been very sensitive to smells. It's so bad that I just want to throw up (even smells I like). And I can't eat anything without feeling nauseous. Like I said there is nausea but I've only thrown up twice. I've been sleeping a lot more as well and I keep getting a lot of white, stretchy discharge. I also have been getting side pains in my rib area. Any ideas?
