Libido in 2ww

Hello Ladies. This month SO and I have been TTC and we timed our BD and all of that. Now that my fertile window is over, I don't feel like having sex anymore this cycle. We just got into an argument because he tried to initiate and I was trying to go along with it and he could sense that I wasn't into it and that got him upset. He says he feels that I only wanted to have sex when I was fertile. We had a good sex life but I feel all touched out after all the BD and I just don't feel turned on even though we haven't in 5 days. Does anyone have similar feelings? Of course my 2ww brain wants to think of this as an early pregnancy symptom but I know it isn't
