Confused need advice!

My doctor recently (monday) had me go on the pill, to try and regulate after stopping the depo last November. I literally just started the pill Monday, I haven't taken it today, BUT today I noticed my cm was very stretchy, like egg whites and very heavy, and my cervix feels super soft and open. My nipples are also super sensitive, and I've had slight mild twingy cramps on my right side. Could I possibly be ovulating?! I took an ovulation test yesterday, and it was negative, should I try again today and tomorrow? I would stop the pill right now if there was a chance to conceive!! Or is this all a side affect of starting the pill a couple of days ago??
