Tired, Confused and ready to give up

We are now going into 6 month of try with no luck. This month having cramps, crying, (not usual for me) acne, tired and at times feel like I want to vomit. Feel like I am ready to throw in the towel and give up. Charting my BBT has become confusing as I don't know what to make of it. Here it is below. Okay, there is my rant ladies. Have a good day and baby dust to all.
