27 weeks pregnant

A quick quick update on where we are
....

We are entering the 3rd trimester
(scary times ahead)

The website tells us:
"Your baby now weighs nearly 875g and will probably measures more than 36cm from head to toe. His eyes open and close, he sleeps and wakes at regular intervals and he may suck a finger or thumb.
Sweet dreams, little baby! Some experts believe that babies begin to dream by week 27. Your baby's brain is certainly active now. The characteristic grooves on his brain's surface is starting to appear and more brain tissue is developing. You may be detecting rhythmic movements, which is simply your baby having an attack of the hiccups. They are common this week and throughout your pregnancy. A spell of hiccups usually passes in moments. The sensation for you may be strange, but rather comforting.
Since your uterus (womb) is now up near your rib cage, you may now find yourself short of breath if you haven't already. Starting now and continuing through the last three months of pregnancy, you may be plagued by leg cramps, hemorrhoids, varicose veins and an itchy belly.
If a blood test for your rhesus status found you to be rhesus negative (RhD negative) earlier in pregnancy, you'll probably be tested for antibodies this week or next. These may be present in your blood if your baby is RhD positive, and you'll have what's called an anti-D injection to combat the incompatibility. You may be offered a repeat injection at 34 weeks."

So indeed i am A- and the baby is + so guess what on Friday off we go to get the anti-D injection....
and this time i will have to go on my own
I am terrified of vaccination and needles in general...
