Giving up

We’re on our third femara/ovidrel cycle, FS will only do 3 round so if this doesn’t work we would have to move on to injectables. My husband and I agreed that if this month is unsuccessful, we’re going to take at least 3 months off and then go back. I feel guilty for wanting to do this but I really do feel like I need a break and just not stress. I feel that if we stop we’re going to waste time but at the same time I just need a break from this emotional rollercoaster. I just hope I’m making the right decision. Does anyone else feel this way?
