Hello I have been experiencing a piercing throbbing pain in

Patient: Hello. I have been experiencing a piercing throbbing pain in my thigh. I started taking hormonal birth control (Nuvaring) about 5 months ago. I have also been experiencing migraines and once had a very brief loss of vision in one eye and numbness on the right side of my face. I am 28 years old, I have never had any health issues before. My question is do you think any of these symptoms indicate the birth control is not safe for me to take? Thank you.
