I was pregnant last year, due late January this year. I declined the swine flu vaccine, figuring I was pretty healthy and didn't do lots of the high risk things - and that even if I caught it the disease was usually mild, even in pregnant women.
Unfortunately for us, the gamble didn't pay off. I started showing symptoms on the 27th December (although we didn't realise what it was at the time), and was admitted to hospital for dehydration and low blood pressure in the early hours of New Years day (swine flu can cause D&V - I couldn't keep water down all day). When we got to hospital they couldn't find our baby's heartbeat with a sonicaid, and 2 subsequent scans confirmed she'd died. I had to be induced a few days later, once I was healthy enough to give birth. SF was confirmed by swab.
Knowing what we know now, SF had been round the entire village over Christmas but the symptoms were no where near what was publicised and so most people didn't recognise it as such. My presentation was apparently pretty classic (according to the lead SF MW) - a bit of a sniffle and a cough for a couple of days, then I felt extreme lethargy (slept for most of 24 hours), D&V starting on the 4th day leading to weird vital signs (BP 60/30, oxygenation 50%, pulse >150). I didn't start a temperature until the evening of the 4th day when I was having a D&V fit mixed in with attacks of rigors (classic flu shivers and shakes). The temperature then came and went over the next few days. The discrepancy in symptoms and the knowledge that I shared them with most of the village makes me think that the cases of SW last winter were vastly under-reported, but also that it was much milder than feared in the majority of people infected.
All that said, I know I was very unlucky - my MW knew 3 other women who'd had swine flu while pregnant, and all of them came through with no problems. And a 4th lady who caught seasonal flu and had the same outcome as me. Part of me wishes I'd had the jab, but I've heard it isn't particularly effective (don't know if that's just people trying to make me feel better!) so I may have been in the same place even if I had. I can't say, hand on heart, that if I could do it again I'd have jab.
Everything in life is a risk, and even more so when pregnant. You can't avoid them all - just choose which ones you're prepared to take.
