I need p&pt!

I am freaking out! My 18 month old has fifths disease. I am pretty sure I had it 2 weeks ago. I had horrible joint pain and a rash all over. My general dr thought that I was reacting to antibiotics, but my sons pediatrician is pretty sure I had fifths. I just had a mc in january, I don't want to go through that again. I have a call in to my midwife about it. I am supposed to go for my 1st appt next Friday. Not sure what they are going to want to do. I think I may go buy more tests bc I haven't had many symptoms other than needing to pee all the time and being bloated.
