I need your help!

So today I’ve had SO much mucous it’s ridiculous. This morning when I wiped I had this HUGE glob of clear snot like mucous. It was such a massive amount. I’ve had it off and on all day just not as much as this morning. I decided not to track this month so I’m not sure if I’m ovulating or if I may be pregnant. It just doesn’t seem like normal o mucous. I’m also having tender nipples, stomach soreness and nausea. Also some slight back pain. Anyone experience this before?!
