I think it has something to do with a hormone that is released when you ovulate that irritates the uterus and other reproductive parts. The area where my ovaries are gets sore around ovulation, and sometimes my uterus. There is a term for it, its German and means pain in the middle of the cycle, I can't remember what its called but it starts with an "M".
The word you're looking for is "mittleschmertz" and it means "middle pain"
Yes - see doctor immediately
Not necessarily. Your symptoms of pregnancy will be missed period, nausea, weight gain, increased sense of smell, swollen tender breasts etc.
The question here should really be when CAN you feel your cervix
Engagement.
First of all, no-one would be able to tell if they were only 3 weeks pregnant (this means a week after ovulation!) if your going off your ovulation, then yes it can feel spongy & swollen - the reason for the swelling is, increased blood flow, therefore your cervix would be blue also, which is very normal.
If your cervix is closed in the front but open in the back, this might mean you are about to start your period. It could also mean that you are ovulating.
The medical term for the surgical removal of the cervix is "subtotal hysterectomy."
Cervix
Through the vagina and the cervix
You mean the cervix? No.
When it get swollen it might be that she is pregnet
If the swollen glands can cause in the neck disease.
