Concerned about my pregnancy

Hello 2nd time mom and this pregnancy IS NOTHING LIKE MY FIRST. First of all I feel like I am having next to no symptoms and just mentally do not feel good at all. I got my beta verified I am indeed pregnant the second I got positive at home tests. My level began at a 15 a week later went to 145 week later 859 a week later 3248 (todays result) . The first day of my last period was august 30 my based on that my calculator estimates me to be more around 7 weeks not 3 or 4. Here’s the other thing that concerns me my hospitals beta chart says I’m around 3-4 weeks currently but every other chart I’ve seen on google puts me around 4-5. Either way I’m still not as far along as what I’m calculated to be based on my last period. I’m hoping my dates are just off and that THIS IS NOT ECTOPIC. But having a week in between each test when it should be no more then 72 hours in between makes me question if my levels are high enough or not. Nobody informed me the tests needed to be closer together until today Plus I’m having light cramping. Do my beta levels sound like they are rising appropriately to you ?! To me they seem low and I’m freaking out :( I’ve tried getting a sooner appt with my ob and she’s on vacay til my next appt also the nurses refuse to tell me if they think my levels are low or rising appropriately.
