HCG not doubling

Hi..need some advice.. my last period was 6/13. I tested at home and was positive. I had light nausea, bloating, constipation, very tiredness.. last Wednesday when to doc and she said urine test was showing light line. Next day all symptoms stoped and I have been without any symptoms. We did lab work and progesterone was 6.6 and she gave me supplements.. my HCG was 700 on wed and next test on Friday was 1177. My HCG only increased by 60%. Since it did not double I had to do another test again today and waiting for update.

Any advice would help. I doubt if I am still pregnant..
