What is going on?

We bd twice last week during my fertile time. According to 2 apps anyway. Then after Friday for 3 days I had heavy watery cm then yesterday heavy white glue like cm now it's clear and stretchy am I ovulating or possibly prego? Af is due the 28th and my breasts are sensitive and my nipples look larger and slightly darker and today I cooked spaghetti and from 2 rooms away could smell the pasta cooking. I'm bloated and haven't been crampy at all or anything like the week before my af like normal. Any guesses ladies?
