I am due to get my period in four days, however, my husband and I have been trying this month to conceive. This morning when I went to the toilet I had a very watery pink discharge. This has now turned into a sporadic light pink think discharge (streak) only when I wipe. I have been feeling very tired, gassy and feel a dull like pressure in my lower abdomen which has been like this for the last two weeks or so. Could I be pregnant or is this the start of my period?
