I don't think I said anything embarrassing in labour. Actually, much to everyone's surprise - my own included - I was incredibly pleasant and polite in labour. I am not on the whole a meek and mild and overly polite person in real life. I mean, I'm really nice and kind (I'd like to think), but when I do get upset, I have a real temper and I can be really mean. It takes a lot to make it happen, but when it does, it's bad. I'm also very direct and bossy. My husband joked he was going to make me write apology cards to the midwives in advance that he could hand out when they left to say sorry for what a you know what I was! Actually, when it came down to it, I was quiet and very polite. I had a home birth with no pain relief at all, but I was really calm, no shouting or swearing.
The only really funny thing that happened was after my daughter was born (we had been team yellow), I went to look to see what she was and even though I was obviously staring at a vagina, I was so in shock and exhausted that my brain couldn't actually tell me what I was looking at. I scooped her up, looked between the legs, stared for a bit, and then was like, "WHAT IS THAT?!?!" I seriously had no idea at the time if it was a penis or a vagina! My midwife was like, "um, she's a girl!". I think they must have just thought I was really dense.
Oh, and I also told everyone afterwards that next time I was having a c-section. I had a totally lovely home birth, but I was so tired at the time that I was like, "I'm never doing that again. Next one's a c-section. I don't have anything left to prove next time!" (Needless to say, definitely having a home birth again next time if all is healthy, it was wonderful, but that's just how delirious I was at the time).
