What are your thoughts?

Hey everyone! So I recently found out I was pregnant. This might be on the longer side so take a seat.😂

I’ve been tracking my periods for a long time and my cycle is usually 30 days. I get my period on the 15-16 of every month. That being said based on that my apps are saying I’m only 3 weeks and 2 days pregnant. I started getting really sore boobs 6 days ago, and obviously they haven’t gone away. I currently have sore nipples, fatigue, a little cramping/ feelings of expanding, bloating, and shortness of breath. I have had 2 miscarriages before but were about a year ago. I remember both times not really seeing much until my missed period. What does it mean that my tests started showing up positive around 3 weeks? Could my Hcg really be that high already? Anyone else have advice or have this experience? Could this be a good sign of a healthy pregnancy? I’m so curious. Here are the tests I took. It’s hard to see in this photo but even the first one I took I could see a vvfp. I’m not sure if these “dpo” are accurate as I didn’t use any opk kits. And the test on the bottom was taken this morning!
