Could it still be an ectopic?

I had an ectopic pregnancy 2 years ago and my hcg didn’t double and they saw it in my fallopian tube. I am pregnant again and on Monday my hcg was 130 and today it’s 442. I’m only 4 weeks. I had an ultrasound done and the doctor said I have a cystic structure but it’s not on my ovary it’s near it .. could this be another ectopic ? Even if my hcg doubled
