i think the concern is your first trimester. However they don't have enough info on how likely it is to have issues even if you've been infected during your first trimester. There isn't enough data. I've also read that many ppl in Asia have immunity bc they were infected when young so it's not an issue as they approach childbearing age.
That being said, I wouldn't be worried if I were in my 3rd trimester. However, if i was planning or hoping to get pregnant, then it might give me pause.
This girl I know is ambivalent about getting pregnant again (doesn't know if she wants three). She's planning on going to Brazil in August. I told her that if it were me, and there's a chance I could be preggie and in Brazil, I might have concerns.
Thankfully I'm almost 45. Very unlikely I'll get pregnant again. So Zika not an issue for me
