Reality vs Myth (pregnancy)

Here are a few things that either I believed would happen from popular culture (episodes of Trash TV and the Daily Mail gossip pages mainly, don't judge me) or things that people have told me...

Your boobs will grow, possible even before you know you're pregnant (this was from a friend, and then a pregnancy book told me I will need to be re measured every 8-10 weeks ish to 'accommodate' the growth)
Reality for me: Nothing. Nada, I will just about fill a B cup. This is one the few things I was actually looking forward to, having actual boobs! but no. Week 18 arrived and I am in the same pre-bump bras.

If your mothers ankles didn't swell yours wont (this came from husbands mother)
Reality: not so far, but I highly doubt that history will repeat itself in any shape or form here, as she didn't even  realise she was pregnant with me till she almost lost me, then was told to drink a can of Guinness a day to help anaemia. She also smoked, maybe that's the secret to non swelling ankles. 3 people I have asked had all said they swelled to gargantuan sizes, and one even had a bone in her foot BREAK because of it. Crutches and a 7 month bump, poor her.

Take it easy and rest up (various people)
Reality: Actually it has been proven that exercising during pregnancy can help to have a  less stressful birth (although obviously if you have been told by a DOCTOR to rest, then do!) and it can also help post-partum recovery, as well as to combat stress and help you sleep better (As if you have any problem sleeping in the first trimester anyway!)  Personally I walk a lot anyway, plus have a fairly active job, and have been swimming when I can and was kindly given some pregnancy yoga classes for Christmas. I really enjoyed yoga but stopped about a year ago when I gave up my gym membership, but it always was an excellent way to de stress and stretch.

"OH MY GOD YOU JUST ATE A PEANUT!!" accompanied by a look akin to that of watching me skin a puppy, followed up with, "the kids going to be allergic now"
Reality: It's complete tosh. Unless of course I was allergic to peanuts, but then eating them would make me a complete twonk.

Use cocoa butter/oil/something so you never get stretch marks.
Reality: If you are going to get them you are going to get them, sad fact of life. However applying copious amounts of moisture will help to keep the skin supple and help the skin heal if you do get stretch marks, in turn helping the appearance look less severe.

You can eat for two now, lucky you!
Reality: I wish. Admittedly some days I am eating more than I should, but if you cant get fat when you're baking a baby when can you? You actually only need around 300 extra calories a day, if you were a healthy bmi when you got impregnated.

If you get heartburn you'll give birth to a baby with a full head of hair. 
REALLY strange woman I encountered at work, really?! just no.

Oh, you FLEW whilst pregnant?
Yes, I did it at 12 weeks and I am about to do it again at 21 weeks. Unless you have been told not to, then it's fine up until the last few weeks, because who wants to have a baby born on a plane? (It doesn't give the kid free flights forever/an automatic passport to where they are headed... I know this because a friend who works for Virgin often had ladies from Africa go into labour on a flight to England  accompanied with a Drs note saying they were only 21 weeks when they were quite clearly full term) However if you DO fly, get up and walk about a bit every hour, and attempt to book a seat near the loo.

Any other ridiculous myths people have mentioned/judged you for?
