About 2.5 weeks ago we had a condom break on us. Stopped immediately and for various reasons didn't get the MAP (already had to take it this year - same packet 
- already had invasive stuff in between then and now to do with a positive smear test and subsequent infection and it was 9 days after the start of my last period in a 28 day cycle). I just couldn't face yet more messing about with my reproductive system for such a small chance.
Last Friday I started feeling queasy and I've felt sick on and off every day since. I've also been feeling more tired than normal for a week, having naps when I can get away with it. Plus some back pain and light headedness.
I do usually get sick before my period but it's always been confined to a bit of dry heaving on one or two days immediately prior. My breasts also feel fine, no different.
My period is due Weds, Thurs or Friday so I took a Sainsbury's test this morning. BFN.
I don't really know why I'm posting. We'd said we probably would choose not to have children so we've already earmarked for a serious chat if it is positive. I just want something to explain (and get rid of!) the constant nausea.
