Miscarriage?

I’m 8 weeks pregnant. My first pregnancy ended in a miscarriage back in September. And I’ve been feeling all the pregnancy symptoms - super tired, morning sick, aversion to foods, sore breasts. However, yesterday afternoon my morning sickness stopped and I had more energy. That’s lasted through today. I’ve had some morning sickness today - but super minuscule compared to what I’ve been having. And I was tired for a little while late morning but it went away and I’m quite awake again. Is this a sign of a miscarriage? I want my baby to be okay and I’m so scared of losing another one...

And if you’re a praying woman, would you mind praying for me? I’m so worried about the baby...
