11 weeks in the clear?

So I’m 11 weeks & 1 day and i woke up today feeling surprisingly good as compared to the last few weeks! I had some light cramping in the middle of the night and on and off this morning but nothing really painful & no spotting. But for the first time in idk how long no nausea/vomiting, no bloating & (so far) no headache!!! This sounds crazy but should I be worried? I get my 12 week testing and ultrasound done next week. Last ultrasound our little bean’s HR was 155 & “strong” as the ultrasound tech put it. It’s sad that the second I stop feeling like crap I get worried if everything is ok. I am SO ready to be in my 2nd trimester!! So should I be worried at all? Any advice would be greatly appreciated. :)
