Wacky Hormones

I've posted quite a bit the past few weeks about endometriosis/missing birth control to now being off birth control. I was experiencing all the signs of pregnancy but it was believed that the pills were making
me feel this way. Well, I've been off the pill for 5 days now. Yesterday I had moderate bleeding, now today I have pinkish spotting mixed with a lot of stretchy discharge.. cramping has returned, a little nausea, and headaches. I also can't seem to keep my eyes open. I know it will take awhile to get my cycles on track but could it be possible I'm ovulating already?
