I need to vent

I'm new to this whole glow app (use it occasionally, but looking to use it more) I'm not really TTC but if it would just "happen" I wouldn't be upset. Well this month I really thought it just happened for me and my SO. My period was three days late I had some symptoms (so I thought) and BAM! Today I'm slammed with the heaviest period. And it couldn't have come at the best time: right after leaving the hospital from seeing my cousin and her two day old baby. Ugh! 😢😳😭 I think my feelings are hurt more than the cramps. I know I'll get past it but I think just feeling like a total jackass is what's bothering me the most. 

Okay I'm done.
