I believe I am due my period this weekend (Sun 3rd Oct)..., however am a bit about the place as only had the merina coil removed on 9th September (only had it for a month). Myself and my partner have been having unprotected intercourse ever since (usually at weekends as he works away). I believe we had intercouse when I was ovulating, but not 100% sure due to my last period being a little early. Therefore, I did a test yesterday (4 days before my period is due, I believe) and it was come back negative. Can it show negative even though I maybe pregnant? I have no period symptoms, but my breasts are very heavy and full. Any ideas anyone??? :)
