TMI but what's the chances?

So I have PCOS and have been TTC for about 4 years. (Yes I have been to their doctors, he's been tested, I've been put on meds multiple times and promised several times by doctors I'll get pregnant within a few months. Yet here we are and still nothing)

Anyways....my period is 2 days late according to 3 apps but sometimes they are off cuz PCOS likes to start my period when it wants to. But I've been peeing like crazy today and between constipated and diarrhea. I've noticed I've been bloated for the past 2 days, been craving carbs like crazy mainly chips and sugary things like last night I had turkey with maple syrup.

I'm scared to take a test because im tired of the emotional rollercoaster it causes. If anyone could give me some hope or at least let me know if this is normal before my period so I can feel more at ease. Thank you ❤️
