Failed first FET ivf

I’m so sad to wake up this am and have a negative urine test . I’m 10 days post transfer and I feel like I will never get pregnant . I have 6 embryos left that are frozen. Why didn’t it work ? This is secondary infertility for me. What is wrong w me that I cannot get pregnant ? I can’t blame this on my husband , this has to be 100% me. The embryos are made, and for whatever reason I can’t conceive . Now I’ll do a second round and then what ? I will go through this 2 week wait and shots and potential failure ? Let’s not talk about the weight gain with nothing to show. I’m so upset . Did anyone else fail their first transfer and have it work for a frozen for the second ?
