Have been feeling sick especially in evenings and did pg test on tues lunchtime..then had tingly nipples yesterday and loads of vaginal discharge so did another test.this morning..still feel awful today, very sick now and heartburn sometimes and then had bad cramps for an hour which have eased off now. I really want to know one way or another.....but feel that 2 must mean that i am not!!!
