Surprise BFP put my mind at rest please.

[ArtfulScreamer]

Well I got a BFP today after AF was 2 days late and to say it's a surprise is a bit of an understatement as my DD who is 19 months was a result of IVF after 5 years TTC without a whisper of a BFP and I've a baseline scan next Tuesday as we were hoping to do a FET with our one remaining embryo.
We weren't using contraception as we didn't think we needed to but this baby is very much wanted but I'm now worrying as I've just returned from a holiday abroad during which I drank, ate oysters and swordfish and went on several waterslides. I know rationally that at this stage there is no placenta and the embryo is living off itself rather than me but mum guilt is a powerful thing.
Please tell me it'll be ok and if the worst does happen it'll just be one of those things and not related to anything I did or didn't do.

Firstly huge congratulations!!! 😄🥰🥳 what fab news for you and your family 💖 please don’t stress yourself out about all the fun you’ve been having. Perhaps because it sounds like you’ve been so relaxed and living life that nature has taken its course and a little bean is on the way 🥰 if it makes you feel any better I had a massive night out with lots of alcohol when I was VERY early pregnant with my first - obviously I had no idea I was pregnant at the time. I told the dr at the first appointment as I was so worried and devastated I’d done damage but he said not to worry at all. I also went on a luge (think downhill go-cart type thing), ate salad from a restaurant, sushi, ham - many of the things they tell you not to eat and do - before I even realised I was pregnant. Everything turned out fine, baby was a text book pregnancy and is now 6 ☺️

Congratulations!

Most of the things on the avoid list are there to avoid the worst case scenario:

Most of the food regulations are to do with the risk of catching listeria which you would know now if you'd had. Swordfish is to do with Mercury and the guidelines are to not eat this regularly as it can build up in the system - so a one off isn't an issue.

A water slide itself isn't harmful, just that you could have an accident on one, harsh landing etc.

I bet most pregnancies have involved the odd drink in the early stages!

Thanks ladies you've helped me listen to the rational part of my brain now to keep my fingers crossed for a sticky bean.
