Earlier than expected (Help)

Chelsea • Rainbow due 7/12/18🌈 Angel baby 7/13/17 👼🏼

Hello ladies I had ultrasound Monday and I thought was 6 weeks & 6 days going off my last period but it only turns out I was 4 weeks then. Today I am 5 weeks and still feeling anxious about being earlier. I had miscarriage in July and I just wanted to know if anyone else shared similar experience and everything turned out okay. Tia.
