Worried...

Just got a BFP this past Wednesday and started experiencing sharp pains in my lower left side today...ended up going to the ER and confirmed there was a cyst on the left ovary which they said was common..dr. also mentioned my Hcg level was 67 and ordered blood work to test again Monday. I took a digital that also gave weeks and I was only 1-2 so I don't except my levels to be high but he also didn't sound like it was OK and said I was too early to rule out an ectopic...just feeling anxious and worried :( I need Monday to he here ASAP..praying my number will have doubled
