A roller coaster

Anyone else feel like pregnancy is kind of a roller coaster? Lol. When I found out I was so excited then I was freaked out cause maybe it was an ectopic, then found out it wasn't. Had an ultrasound at 6 weeks 1 day, and measured 5 weeks and 2 days only and had extremely high hcg levels. So I was freaking out thinking something was wrong, possibly a blighted ovum. Then I had an ultrasound at 8 weeks 1 day and saw a heartbeat. And I'm ecstatic. But still worried. Anyone else feel like although your happy, you're still extremely worried?! 😅
