It seems to have only lasted 24 hours and I have been to the hospital where they monitored me; the baby had gone very quiet throughout the vomiting episode. I feel a bit better now but I am paranoid about some frozen cream I ate jut before I became unwell. It was just frozen whipped cream which I had got out of the freezer. I had let it soften for a couple of hours but it was still quite hard and cold when we ate it. I am now googling listeria madly and convinced this is what has made me so sick. Does anyone have any thoughts? Thank you.
a couple of thoughts - listeria is rare, most often causes a flu-ey illness, most likely to get it from cook-chill meals, pre-prep salads, soft cheeses, not frozen cream. Average time for the illness to develop is 30 days (so not normally right after you ate something).
If your cream was pasturised it won't have had listeria - pasturisation kills the bug.
Hows the baby now?
If you are still worried, see your GP or midwife or both - there are tests for listeria infection if you are really worried.
Thanks so much both for your replies. The baby is moving well now and though far from feeling brilliant, I am miles better. I find it really hard to get perspective on anything as I have had an infection in pregnancy before which ended in stillbirth, so it is really useful to get an opinion beyond my own worrying.
