Early baby!

So I'm due March 24th.. yesterday I had bad Braxton hicks contractions, very regular, lasting 2-5 mins each time! They went on all day constantly!

In the end I called my maternity ward and they told me to come straight in, they ran loads of tests, and I had a high chance of going into labour! I'm currently only 33w4d. But he's measuring 38w5d! Every single scan (even my dating scan) they said he's measuring a little big? Why wouldn't they just say the date he was measuring.. and originally my due date was end of Feb!🤔 so my constultant will be very surprised if I make it another 2 weeks, if I do he wants me to be induced end of February because I just wouldn't make it end of March, a whole nother month! Anyone else been through similar?
