Is this the month?!!!?

I have had a lot and I mean A LOT of watery CM. To the point where I have had to wear a panty liner. And my breast have been extremely sore. Mostly my nipples and the sides of them. Oh and before the CM I had two days of slight spotting and cramping. I am not sure when I ovulated or when my last period was because I was on birth control for 5 years until 4 months ago. What do you guys think?
