On Monday, so 5 days ago now, I woke up with severe nausea and diarrhoea. This continued all morning but by the afternoon I was feeling fine again. On Tuesday I woke up feeling ill with diarrhoea again but after an hour or so I was perfectly fine again. Since then I have been on and off feeling nauseous, getting hot flushes and slightly dizzy spells. I have found that I cannot eat as much as I usually can, half a meal I would usually eat leaves me feeling really nauseous however I've not vomited. I'm concerned I might be pregnant. I did a pregnancy test on Monday morning but I think it may have been too early. My period is due on Monday next week, I have sore breasts and although I'm on the pill the time I take it varies largely.. Could I be pregnant? Should I take another home pregnancy test on Monday??
