My period is 21 days late as it usually comes down between the 24th and 27th. I took a pregnency test 2 weeks ago, but it was negative. Now I am way over due, no signs of a period. Lately I am always sleepy, fatugued, and I get dizzy spelled. My boobs get sore at the tip out of nowhere, and my lower pelvic is itchy and at times sore. I keep feelin uterus pinches in the pelvic and uterine canal for a little over a week now, and I am confused. Can it be a false pregnency, a illness or cervical cancer. I would love some advise, as I already made a appointment for a blood test, I would just like some information or advise as to what to look out for.
