Feeling kind of funny...tmi

Ok girls I need some advice. This month my "period" only lasted 2 days and it was never more than what would full up a small tampon. It was really dark and rusty looking but that's usually how mine starts off anyways so I wasn't to concerned but it never got brighter or heavier and it only lasted about 3 days where my period usually lasts about 5. According to glow I would now be cd15 and I should be in my fertile period but I haven't been using opks this month due to a lot going on and not having to much money to buy any right now so I don't know if I actually ovulated or not. The last few days I have been peeing like crazy and I've been feeling very nauseated and today my boobs are sore to the touch. I have a ton of cm which is fairly typical for me when I do ovulate so I didn't think much of it until last night when I started to feel sick on my stomach. Today that has been persistent feeling and even though I don't feel like I could throw up, I still can't eat much without getting queezy.
