Possible ectopic.

So on Tuesday and Wednesday night I was woken up by the most excruciating pains. Wednesday was far worse than the prior night. It was so bad I broke out in a sweat. Tuesday night was period like pains that was in the centre and Wednesday was localised on my left ovary, 10x worse and radiated down my thigh and into my knee. Luckily I had a prebooked doctors appointment yesterday so the following afternoon I went to my appointment. During the exam the doctor seemed really concerned of ectopic and sent me and DH to the ER. We spent over 8 hours there. I had bloods taken, urine sample taken and u/s (transvaginal and abdominal). Not to mention a failed attempted at giving me fluids. I was so dehydrated they couldn't find a vein. LMP had me at 4 weeks 1 day yesterday and the nurse told us my Beta HCG was 1308 😳 much higher than I expected!! Nothing was picked up on the U/S because it's too early and/or ectopic (which is what I expected to see). They've asked us to come back in tomorrow and Monday to check beta HCG and get an ultrasound on Monday. I'm so worried its ectopic. This is my first pregnancy EVER (no idea why I put that in caps!). DH is just happy I'm pregnant and doesn't get we're not out of the woods yet. I think he's upset with me too that I'm not jumping from the rafters like how he wants to be. My sister had been through this too and I'm just all over the place at the moment. I don't know how to feel or what to do. All the people who examined me yesterday started off so happy and by the time they finished they looked visibly sad!
