Feeling a little discouraged this month :(

I guess i just need to vent... my husband and I have been trying for over a year. I have endometriosis, and read that I have a 3.3% chance of conceiving. My heart broke a little and I just feel like I’m already out this month and I’m only 3dpo. When I was younger, i never thought trying for a baby was going to be so hard.
