Pleurisy- what in the world??

I've been trying to feel "normal" again and since I stopped taking the prescription pre natals my digestive system is getting better. But the chest pains on the right side came back a few days ago. My family Dr. thinks I have pleurisy which is fluid in the lungs and put me on antibiotic (generic Z pack). After much hesitation and a phone call to midwife to ensure its OK. I started the antibiotic last night because pain was getting worse and I was scared to not take it because I don't want to risk getting really sick with something when I could of prevented it. I was just trying to stall to see if would get better on my own- but it didn't happen. I really hope it works and I'm done with health issues for a while. I can't wait until my next appointment. 2 weeks from tomorrow. I'm almost out of my first trimester! Woo Hoo!
