Advice

Hello. My boyfriend and I have been ttc for the past 3 month, last ovulation cycle we did the baby dance the day I ovulated twice. On glo it said I was suppose to be due for AF August 29th and I did not, the next day I had very light pink when I wiped but that is it. So glo changed it and said I was suppose to be due for AF September 1st, so that day I wake up no AF just very little slight brown stuff in my underwear and when I wipe slightest but if pink first wipe but nothing else. I continue to dress and put on a pantie liner, about a hour and a half later go to the bathroom and have a spot smaller than a dime of the brownish discharge but nothing when I wipe. I have not tested yet because I don't want to get my hopes up. What do y'all think.

P.S. I have been having mild cravings, spontaneous lower stomach cramps, nausea, and urinating more.
