Thank you for your query.
I think you should consult your gynecologist as soon as you can.
The kind of pain and dizziness you describe is not normal for pregnancy.
It could be the sign of an impending miscarriage
ALso rarely an adnexal or ovarian cyst
could cause such pain and dizziness on pressure.
rarely, a bowel infection or a pelvic infection
could cause such symptoms.
However, please get medical attention and a proper examination and ultrasound
if possible for probably causes.
