I feel like I am hopeless in the ttc journey.

So, I am 6 days late. I have not taken a test because I know my period will be here. I am an odd person when it comes to period symptoms. I have been here before and do not feel I have been overly stressed. The problem is my symptoms of pms are odd cravings, mild cramps, nausea, diarrhea or constipation. Today, I have craved mustard and pineapple topping sandwiches. I will be 40 in Aug. and seem to have lost all hope when it comes to being able to have one.
