Anyone else completely mad at their body?

So here’s the thing, I haven’t had a period since September. I started taking Myo-Inositol and it seemed to really help! Fast forward to a week ago, my boobs started hurting a bunch and were heavy! Since then, they’ve gone back to normal, occasionally hurting. On the 22nd I got a vvfl, and since then I’ve gotten only negatives.( assuming this was a false positive). Part of my brain thought, oh maybe it was just too early. Today I tested negative and I’m completely heart broken. I don’t understand what my body is doing and why I’ve never gotten a positive OPK. I feel like I’m wasting money every month.
