I'm not sure if somebody else has posted this before, but i thought i'd start a new thread so here goes.
I was due on my period on sunday, and me and my boyfriend have been trying for a baby (we were intimate every day for two weeks over my ovulation) but my period is late. I have a few symptoms such as feeling really sick and being sick about 3 times a day minimum, I have stomach cramps like period pains, and I also have back pains. I have a metallic taste in my mouth and have been put off pretty much every food that i like. and my breasts are very tender. I have taken 3 tests, the first two were wishful thinking 4 days before i was due on then on the first day of my missed period (these were just superdrug's own tests) but i also tested today (wednesday) and got another negative with a first response test. still no sign of my period though.
anybody have any suggestions, and also, what in your opinion is the best test to use and how long to wait to be sure its a definite negative/positive?
anything would be a great help,
