Early pregnancy help

Hey everyone so today hubby and I went to the first ultrasound apt today. This will be our third pregnancy we have one beautiful daughter we then had a miscarriage early 2020 and now pregnant. Went to the ultrasound today pumped to see baby well the ultrasound tech said you might be very early because we only see the Gestational Sac the office will call you Monday (48hrs) I'm just getting very nervous she stated I'm only 4 week 5 days and its very hard to see anything at this point can people relate to this I'm not saying she is wrong I'm just feel silly going this early and also feel to think this could be a miscarriage I am in between hope right now help a sister out please I Pray to God this is going to be a Rainbow Baby please pray for us 🙏🙏🙏
