CAS and gender reveal experience. FTM

Had the CAS for my baby yesterday. Everything's normal and we are thanking God for it. My husband is really expecting for a baby boy, so before undergoing the CAS, I prayed to God na sana i-grant yung wish ng asawa ko. But then when the doctor said, "you will be having a baby girl", nagtinginan kami at nagtawanan ? We know kung bakit kami natawa e kasi maling expectation ? but the good thing is that, there's no disappointment na nakita sa mukha ng asawa ko, only happiness. Thank you Lord , our baby is healthy ???
