Thanks for discussing your problem to us.
I think you have two problems. One is menstrual irregularity & second is high blood pressure
. The symptoms you quoted are quite non specific & are present in a number of conditions. If you are in doubt about pregnancy
, you may go for a blood pregnancy test & a trans-vaginal ultrasound
. These test can also provide you with helpful information regarding any problem with your uterus
In addition you should see a gynecologist for diagnosis & treatment of your menstrual irregularity and also contact a physician for blood pressure control.
