Early Symptoms?

Hey mommas, AF is due in 5 days (I haven’t tested yet). For the past week or so I have had really minor cramping in my lower abdomen at night. Kinda like a bloated feeling but my upper tummy doesn’t feel hard like usual bloating. My left breast is sore along the side along my armpit and is enlarged. The other one is normal aside from a blue vein. I’ve also recently seen a large increase in clear CM, nothing is really there to touch but it’s wet on my underwear. Do these sound like they may early pregnancy symptoms? I am trying not to get my hopes up too much and I’m nervous to test too early and get a false negative result. I haven’t really experienced these symptoms before AF arriving.
