Transvaginal ultrasound

Hey all,

So... I have got a transvaginal ultrasound booked next month & it falls the day after our wedding anniversary, so obviously that night it’s likely we’d have sex...

We don’t use protection as we would be happy if I ended up pregnant, we have the view of “if it happens, it happens” - is it a no-no to have sex the night before a Transvaginal ultrasound?
