Low hcg

I had a Quant hcg on 10/3 it came in at 63. On 10/8 it was 89. I have only 1 ovary and a damaged tube but have had a successful pregnancy under the same conditions. Vaginal ultrasound had a gestational sac and measured at 5 weeks exactly. According to the app I am 4wks 5 days and have only had positive hpts. Should I be worried? No cramping or spotting. Just sore breasts, heartburn, and occasional nausea.

Update: hcg has continued to rise. It doubles about every 3 days. Doctor refused to offer another ultrasound despite me offering to pay cash. Last night I had red spotting when wiping but nothing on the liner. Went to er. They did an ultrasound and confirmed it's not ectopic but either too early or I am in the process of a miscarriage because there was a gestational sac but contents were to small for measurements. I was told that I was not allowed to even see the scan bc I was in the emergency room and dr was unwilling to discuss if he saw a yolk sac or fetal pole. He did say my hcg was at 580 so it is increasing approximately 37% every 2-3 days. Has anyone been through this? How did you deal with medical providers that were unwilling to communicate and involve you in your own care plan? I am planning to contact a specialist as my blood pressure was 175/115 and they did not even attempt to lower it. I naturally have elevated bo that I control with diet and exercise but have noticed with this pregnancy my bo is still elevated and dangerously high yet the ob is too obsessed with my hcg to even address it.
