Really bad cramps?

Kayla

Here is my chart so you can see where I am with everything. Hubs works away right now so this month is kind of out I’m thinking. According to OPK I should have ovulated yesterday or today. However starting Wednesday I have had severe cramps almost like period cramps (They are intense !!) and I am so tired and moody, that’s not my usual for around when I ovulate? Anyone else experience this before?? It’s really strange for me.
