Speak to your gp / midwife about ziks risk for sure
Congratulations! I was in a similar situation in that we were planning to go to Vietnam. I think zika can affect babies throughout all of pregnancy can’t it? And having an early scan doesn’t mean you won’t get zika. Im sure it’s highly unlikely that we got zika but at the same time I’m not sure how good counties like Thailand and Vietnam are at reporting their cases… Personally, we decided to cancel the trip, I don’t think I’d be that relaxed while there. If you’ve already paid, could you delay the flights and hotel? Apparently Thailand is a nice place to visit with a baby
Not sure where you’re from but here in the UK, you can get a private scan that early and they refer to it as a “dating scan” to essentially figure out how far along you are and they check for a heartbeat. If you’re anxious, it’s definitely something that would put you at ease before you fly away
