Nervous! Advise?!

La

I am 7w6d and I had nausea beginning around 6w and I've also been very tired. For the last 3-4 days I haven't experienced significant nausea, but I am still tired. I had a MC back in May and a couple days before it, my symptoms decreased. I'm wondering if you guys have experienced this fluctuation in symptoms or if I should be worried??! Advise please! Thx in advance
