I'm 34+5 and I'm still waiting for the morning sickness...lucky me!
What I have had though is the following:
Insane tiredness, mild heartburn, itchy skin, backache, frequent loo visiting and a little bleeding in the first trimester;
Energy bursts, nausea (for about a week) but no sickness, skin rash, and swollen ankles (during the hottest part of the year) during the second trimester;
Now in the third trimester I have evil pain in my pelvis and have been told to keep my knees together at all times, (scary woman from Ladette to Lady would be proud) tiredness and absolutely no other symptoms at all apart from an inability to sleep for more than 2 hours without requiring a trip to the loo.
What I've learnt is that every pregnancy is different and if you are worried, seek advice from the midwife.
Good luck with the pregnancy and enjoy it - it goes so quickly!
