12wk scan is at half 2 today and I have the usual nerves like will everything be ok etc but are there statistics showing how common twins are? There's twins in my DP family but none that I know of in my family. I've been really rough with morning sickness this time round which I've found out can be lead to multiple babies and everywhere I go there's twins, and to top it off my DP had to take this afternoon off work to come with me and someone asked him what the odds on us having twins are!? Think I'm being a bit paranoid, please reassure me, really don't think I could cope with twins!!
