I have a 2yo and since having her my pain during my cycle has gradually gotten worse. I used to be able to have sex during my cycle with no problem but now it hurts so bad I cant bear it. We are trying for a second child before I turn 40 and no luck. Two times my period has been weeks late and then horrible when it came. Some one suggested that the egg fertilized but wasnt able to implant. All this has me wondering if something more may be wrong.
