Nervous

I am 6 weeks today and suddenly it almost feels like I’ve lost symptoms out of nowhere. Yesterday I was pretty nauseous all morning. This morning I was slightly nauseous but it’s went away. I am pretty fatigued and hungry often. My nipples are sensitive and sore too. But I just think it’s weird that now I don’t really feel nauseous? I had some bleeding on Saturday with no cramping. I had an early ultrasound due to it but everything looked like it should. Idk it jsut scared me. My back is slightly sore and I’ve had a few mild cramps today but no bleeding since Saturday. I hate this wait game :(
