Welcome to Healthcare Magic
Regarding the menstrual problem it could be due to Asherman's syndrome. It the D&C was done harshly and deep, there may have developed scarring inside the uterus
causing very less menstrual blood to come out of the cervix
. This means a lot of blood is still inside the uterus which gives you the feeling of pressure on the cervix. Do you have any problem with urination and stools. Meet a Gynaecologist. He/She will examine you and may take an ultrasound
scan which will tell if you have this problem and then proper management of the problem may be undertaken.
