“Prep month” after failed FET?

J

So I had my retrieval in Nov and did PgS testing. Got great results and did a FET with a 5 day embaby on dec 8 that was normal and a high grade. Got a positive beta on dec 18 and was happiest woman on the plant. For ten days. Then after third beta my levels dropped and they said I’d be getting my period. Have been devastated. They suggested I do a “prep month” and so I’ve been taking birth control and luprolide shots. They explained to me several times what the “prep month” does (prepares my lining) but I still do t understand because my lining has always been super thick and great and never a problem so I don’t understand.

Also, They still haven’t scheduled my next try at a FET. Anyone else have success stories? Please share any similar stories that had a successful outcome. I feel like I’ve been through a war already.

Anyone gone through this “prep month” without a previous problem with the lining and had it work for them??

Thank you and baby dust!!
