1st FET failed 🙁 1 embryo left - any advice for FET 2 feeling sad & defeated

Just received my negative from the clinic today was the worst wait ever. I did accupuncture the day of (pre and post transfer) and a few sessions before. The week post transfer I ate pinapple core + meat, Brazil nuts, avacado, had soup every day, drank hot water not even decaf coffee/tea. Drank lots of water at room temperature. Wore socks. No working out all for the straight 2 weeks. I had tested at 7 days past with a BFN and was upset but had hope. We only had 2 embryos so 1 we just used and didn’t work out and one left. Now I’ll be off my meds and I should get my period within a week. I’m sad and feeling defeated looking for advice anything. The worst thing I feel is what else could I have done I did every technique I found, googled, Pinterest you tubed you name it. Keep my head up for the 2 weeks praying and lighting candles daily. Tried to be stress free. On leave at work at the moment. Just feeling defeated. 2 failed IUI and now 1 failed IVF I’m so worried and scared would hate do another ER and start all over again. The visits the meds it’s draining. I try not to complain there is worse off but its hard was hopeful the IVF would work the first try.
