My boyfriend and i have been trying for a baby for a 4 months now. I came off my contraceptive pill 4 months ago. For the last couple of weeks I have not felt myself. I am very tired and emotional. We took a pregnancy test last week before my period was due and it came back as negative. On Monday this week my period came for half a day, very light in colour and consistancy and since then it has gone. Is this normal?? Could I be pregnant??
