Im tired of being a failure 🥺

I’ve had the toughest year and a half and things aren’t getting better. Long story short. We got pregnant from a fresh transfer in March 2019 but It ended in miscarriage. Ever since then my lining gets thick but wont be trilaminar. We decide to not do estrogen pills and try Gonal f so my body produces estrogen naturally. Nope that’s still not working. I feel so helpless and lost. Nothing ever goes right. I had no issues with the 3 layers before and for some reason we just can get them. I do have a tilted uterus so maybe they just can’t see It? Idk. I’m so lost and feel like such a failure
