Weird symptoms mid cycle

Caitlin-and
Hello Ladies! I've had some weird things going on. My opk's have been registering fertile for 4-5 days, I've had some very light spotting during and after ovulation lasting about 4 days, and it's about 2 weeks til AF is due but my breasts are very sore. Anyone experience this before? This is all new to me.
Thanks for any response!
