What is going on - sore boobs

We experienced a loss in October and since then my cycles have been very irregular. My last one started December 25. I have no idea if I’m ovulating or not yet, but there were three days earlier this week that I was experiencing lots of watery discharge sometimes similar to EWCM. Since then the discharge has disappeared but now I have had such sore boobs and nipples and a dull ache above my right ovary.

Obviously we are trying to get pregnant again, and I think it’s too early to test, but I’m just wondering if anyone else experiences sore boobs during ovulation?? Or could it be something else?? I have only ever had sore boobs when I’m pregnant, never during my cycles.
