TMI sorry but curious

Elizabeth
Hey everyone sorry if this is TMI but I'm looking for anyone who has any insight. I had a miscarriage about a year ago and my husband and I have been trying again ever since we were giving the go ahead from our doctor. So now I try not to rush into buying a pregnancy test
I'm normally pretty regularly 27 day cycle and I'm on day 30 no period although I am cramps or my accurately feeling gassy. I keep thinking my period will start but nothing. I also have a milky lotion like discharge. 
Has anyone had these experiences? Were you pregnant or just late for some reason. 
Thanks for your insight
