Feeling Confused and Frustrated

Soooo the reason I’m confused is because last month my AF only lasted a day and a half, that’s not usual for me and around this time according to Glow my period should have been here three days ago.... I’m getting all these symptoms that I normally would for my period and it’s getting frustrating due to the fact that me and my S/O are TTC. The two main symptoms I’m having is sore and tender breasts, mild cramping here and there and I’m constantly hungry and tired. Could y’all tell me what you think it could be... could it finally be my chance to have a child or could it be AF messing with me. I don’t wanna get my hopes up on thinking I’m pregnant due to the fact that I’ve miscarried twice so far and it kills me everyday. If you could comment your honest opinion on what you think may be going on I would greatly appreciate it
