7 wks 5 days pls read and comment thanks

Hi.. just looking for some advice or opinions . Tomorrow is my first ultra sound i should be excited but instead I’m scared to death that something is going to be wrong .. I’m scared there will be no heartbeat or just a sac.. at abt 5 weeks 5 days i had spotting when i wiped only lasted abt 3 wipes and i would have never known if i didn’t wipe didn’t have any cramping with it ..3 days later went to my first prenatal appointment and had blood work done got a call back a few days later said blood work looked normal and scheduled my ultra sound . So far I’ve just had sore nipples , haven’t been hungrier however i have been eating all the time bc that’s just me 😂 I’ve been peeing more sometimes & having vivid dreams just abt every night . I’ve been have fatigue also but that’s all. One thing that also makes me worry other than that spotting one time is my lack of symptoms compared to my other pregnancy from where i had bloating from the beginning which i haven’t had at all yet & I’ve also been very dry down there compared to last pregnancy when it was the complete opposite . Last pregnancy around this time i would feel sick if i didn’t eat this time i haven’t had that . I’m so worried ... i also have had some sharp pains on sides at times but i did have a ultra sound at 5 weeks after spotting which it wasn’t transactional so you couldn’t see much but they said sac was measuring right and in the right place .. if you could pls comment your opinions it would be helpful and mean a lot .. thanks 🥺i just needed to vent
