I am so emotional right now😩

This is our 5th cycle ttc and I am now 4dpo. We have had 4 chemicals since January and I really don’t kno if I can go through another one. I do believe I have luteal phase defect so I’ll get a faint positive on like 9dpo or 10dpo n 10-11dpo everything is over with and I start my “period”. I am praying that this month will be different since I am taking more supplements, vitamins, and taking progesterone cream. I just want to get a positive and it stays that way.
