Hi, i am 37 and have been ttc for 2 years.  My cycles are generally 24 to 25 days and are regular, although i did have a period that was 29 days apart fairly recently.  My last period started on 6 jan but then roughly on 15 Jan i experienced brown/pink discharge for about three days with a small amount of red.  I have never had this before and it was not like a period as it was quite light.  My period would have been due around 30 Jan up to 2 Feb if i was to go to 28 days, however all i have had was a lot of milky discharge (there is no odour, itching etc) and my period has not yet arrived!  Could i be pregnant?  I have not tested yet or could this be an indication of some other health issue.
