4 weeks 2 days Pregnant

Hi all. I have confirmed through pregnancy kits that I am pregnant and my Gynae also confirmed. I am currently 4 weeks 2 days and experienced some headaches, cramps and bloatedness at times. As my ultrascan only can be done at week 6 (in order to see baby’s heartbeat), is there any way to know how baby is doing? Is everything ok? It’s my first pregnancy and I don’t know how to tell if everything is alright.
