My nearly 2 yo DS2 has 5th disease/slapped cheek. The rash started showing on Saturday, so although he's not contagious any more, I was probably exposed to it a week or so ago. I got a bfp on Friday (the day before he got the rash). I'm going to ask my doctor to run a blood test when I see him next week and am hoping I am already immune. But, I just wondered if anyone has any experience with this during pregnancy? All the stuff I find online talks about increased danger during 1st and 2nd trimester, but my exposure was probably just after conception - I'm wondering if this makes things better or worse. It's taken me a good few months to get pregnant this time, so I'm terrified of anything going wrong :-(
