Eeeek no experience, but hopefully your experience this time would be easier as you would know what to look out for.
I had a day feeling NOT SICK yesterday! Unfortunately, it is back with a vengeance today :( Also have developed a v nasty cough just in time for the first day of the Easter hols, and we are off to Brittany on Monday. Aaargh! MIL has had terrible flu that started with a cough, but I have had the jab, so am crossing fingers that mine doesn't develop into anything nasty.
On the lovely side, am definitely feeling movements now :) Much teenier and weenier than I remember it feeling with the others, but I was about 22 weeks before I felt anything either other time, and am 17+3 today.
