Car accident and found out I’m pregnant few questions !

My 14 year old and got rear ended last Monday. Guy was going like 60 when he hit us. My daughter and I are both super sore but they couldn’t xray bc they came in and told me I was pregnant the next day at the er as I was having terrible pain in my finger like it’s broke and abdominal cramps and much more. So I found put on the 23

App puts me at 6 week 2 days however I had to go back to the er two days ago and they tested my levels and did ultrasound and the measurements they printed for me said I was 5 weeks one day. So I’m going to go by the measurements. Of course we wouldn’t show me the screen or anything.

My hcg level was 2688. That seems high for 5 weeks or is that normal. Is it normal to have such cramping? Suppose to go tomorrow to see if it has doubled

We have tried for 3 years. I gave up last month and threw out all of baby making supplies 🙃. I told him all I wanted for Christmas was to be able to share good news we were finally pregnant. We have tried the old fashioned way no help. I have pcos and I think a cyst ruptured and everything was clear and ready. All I can think of besides Gods timing is not our own.
