Re: I dont know if I should be worried or not please help
Call your doctor now. There should be a doctor on call for your doctor if the office is closed on Saturday. Since you're swelling, have a headache, and pain you need to be seen and evaluated to make sure all is well. You may be told to go to the ER. This should not wait until Monday or until your next appointment. You can also just go to the ER and if there's a need, the staff there will get in touch with your doctor or with the doctor who is on-call.
It's really early for pre-eclampsia, but you cannot be too careful.
