First and second HCG levels??

Hello! I was wondering if anyone that remembered, could tell me what their first and then their second HCG levels were at and how far along they were? This Sunday I found out that I'm pregnant. I had gotten the nexplanon put in on August 14th and my test was negative when I went in. I was on birth control pills for about a week and a half prior to the nexplanon being inserted. My Dr is pretty sure I got pregnant on the pills and it was just too soon to show up when I got the nexplanon. My hcg levels Sunday were 280. Tuesday they were 757 (I got the nexplanon removed on Tuesday). The Dr put in a req for me to go in tomorrow to be tested again to see where I'm at. They're wanting to schedule a transvaginal ultrasound as soon as my levels are high enough to see exactly how far along I am. I've got an HCG level chart on my phone. I'm just wanting to try to compare some levels with people.
