This is my 2nd pregnancy, 1st pregnancy was a blighted ovum, so I'm paranoid about everything. I had an ultrasound last week at 7 weeks 4 days, a heartbeat of about 165. Over the weekend I was sick & had a fever that spiked up to 101 for a couple of hours. By Monday my fever was completely gone and on Tuesday I noticed that most of my pregnancy symptoms were gone. I'm not continually nauseous anymore and my boobs basically feel normal. I'm 9 weeks today. Is this normal or should I be worried?

Thank you.
