Rainbow baby? or another storm 😥

Last year, the same month, August 2023. I had a miscarriage at 7 weeks. No bleeding , No morning sickness ,and No Heartbeat. This year, August 2024 . Tested positive sa PT and currently at my 6th week of pregnancy . Hindi ko sure if i'm happy dahil parang nangingibabaw ang takot na baka maulit 🥺 I cant sleep dahil gusto ko na sana ma-ultrasound para malaman ko kung may heartbeat ba sya 😔 kaso suggest ni OBgyne sa Aug15 pa. I don't have any morning sickness at nawala din ung soreness sa nipples ko. (just like last year)
