Bummed yet again.😞

I was so sure i was pregnant this month. Granted this is only our second month trying but still. I try to prepaire myself for either outcome but more so the AF outcome because that's what I'm used to and yet when AF shows up I am still all depressed . My SO says it will be ok and we will keep trying but I can't help how I feel now in the moment. Does anyone else go through this and how do u keep yourself to stay positive? I just hate being disappointed every month when my cycles are same time every month. And everything else seems normal. I don't know I'm just blah I guess lol congrats to anyone who did happen to get their BFP.
