6 weeks pregnant, first pregnancy

I spotted on the day my period was supposed to start and took two tests after I completely missed my period. Both came back positive. Since then I have had frequent fatigue, my breasts have gotten a little bigger and sore, and a couple days ago I had a REALLY bad hot flash in the morning (my first one ever, in fact.) On the same day as my hot flash I also had some brown spotting during the day, which I read that it is normal unless bright red and thick. I haven't really had any kind of cravings or morning sickness (yet?) I'm also feeling a little bloated. I've also basically had light cramps every so often daily since my period was supposed to start. Usually at the start of my period I have one day full of really bad cramps.

Today I just feel meh and I don't really feel like eating, but am anyway. I'm also taking prenatal vitamins. Tomorrow I have my first appointment to see what we can see on an ultrasound. I'm actually a little anxious that my body is just playing a huge trick on me and I'm not actually pregnant. 🙄

My boyfriend and I have been together a year and a half and know for sure we are getting married, and we planned on doing that before having any children, but plans change! We are only 19 and 21 but we are greatly looking forward to our baby (and hope for a little girl ❤️)

Wondering if those of you that have been pregnant before feel that this is all normal!

Also, this is how my tests looked (not my photo, but exactly the same) and I read that it is basically a super-positive, meaning the hcg levels were so high that it pulled the dye from the control line to the result line.
