Hi everyone

I have had cramps/dull aches since ovulation (predicted 1st Feb) I have a 25 day cycle and I’m very regular. I’ve been off the pill since November 2017. I had a sore left nipple it was constantly erect a few days after this but that has now gone. I have had pinching and what feels like small quick sharp pains also. I had increased CM weekend just gone which I don’t get before my period, and I have had horrible nightmares and vivid dreams for around a week. Today I was checking my CM and cervical position I had watery discharge but then as I kept checking I had some watery blood, then a dark rust colour it has now stopped. Can someone help me feel sane, I’ve never done this before I’m 25 and this is my first big guess of if I’m pregnant or not.
