FET in July

Hello everyone I had ICIS last July the cycle was perfect but I lost the baby at 3 weeks and 4 days we had been trying for 5 years and it was crushing, now next month we are trying our frozen cycle and I admit I wasn't nervous I was existed but now it hitting me again I'm praying it all Gos well and that if it works pregnancy will last I'm so terrifed we will lose the baby again, if anyone is going through the same thing how are you feeling, xxx
