Thanks - I'm hoping this was the case; we were also using lube so it could have been that too. Most likely nothing to worry about.
I'm not planning much more sexual behaviour for a while so it's unlikely I'll go back on the pill until I've made a conscious decision to become consistently sexually active again - this was a bit of a surprise to be honest. However I usually keep myself quite well-informed about contraception - there's actually a pill available in Ireland that's effective for five days after intercourse as well, which is handy to know about!

Anyway thanks again for replies.
