5 days late... Emotional... Just kinda venting!

So I'm 5 days late... I have been crying A LOT and I hardly ever cry like this! I'm also under quite a bit of stess, even though I try my best to not stress. My periods are pretty much always on time. Me and my husband have been trying to conceive for 3 months now. I'm wondering if maybe I am pregnant??? I have been so crazy emotional lately. But that also comes with fixing to start period too. Normally I'm not like this though. I usually get a little ill or moody before I'm about to start. This time just feels different. I don't know. Fingers crossed though that there's a little blessing growing inside me!! 
Thanks for listening lol. Comment with any thoughts.
