Shaz, swelling can be normal during pregnancy. But it can also be a simptom of pre-eclampsia. You can go to a pharmacy or clinic (i know the medicross clinics do it for free) and ask them to test your blood pressure. If is is high, request that they do a urine test. This should cost around R12. That way they can see if there is a problem and you can sleep better knowing.
If there is a problem, they will tell you to go see your docter or go to hospital.
As for which gyni and doc to use, sorry I'm in Jhb so I can't help you there.
Just for interest sake, what medical aid (and plan) are you on? I'm thinking of changing mine.
