Unfortunately I don't know how but I was diagnosed with chlamdyia at my first prenatal visit. I got the call yesterday and immediately got my medication and took it. Spouse will be getting tested and taking his as well. I think I got it before him and i just never had any symptoms. Who knows we are over it and just want to be treated. Do I still take my prenatal vitamin with the two pills I took yesterday or what? I've got the runs from the pills and throwing up from the pregnancy.
