Could I Be Pregnant?

My period is due in about a week. I’ve never had breast soreness before in my adult life, but my nipples are super sore and sensitive on and off right now. I’ve been a bit nauseated the past few days as well, and have thrown up twice. I’m tired and a bit moody. I know I’ve already ovulated for the month, but for the past few days I’ve had super watery cm, with bits of stretchy cm coming out from time to time as well. Has anyone else had stretchy CM and ended up being pregnant? Thanks guys, I’m just trying to ease my mind until I can take a test.
