Do I need a second opinion?

Wondering if I should seek a second opinion.

Back story;

I found out Wednesday that I am pregnant. I did have an ectopic last year in august.

I had an ultrasound yesterday. Nothing was seen. Not even in uterine. I tried explaining to my doctor that it is 100% IMPOSSIBLE for me to me anymore than 3/4 weeks pregnant. He insists on using the date of my last period, which would make me 8 weeks today.

He INSISTS I get methotrexate, because he is “suspecting” another ectopic.

He isn’t listening to me when I tell him it’s impossible for me to be more than 3/4 weeks pregnant.

My blood work showed my hcg is 100, which is consistent with being no more than 3 weeks pregnant. Same with my progesterone levels.

Which would also explain why nothing was seen on the ultrasound. No sac develops until 5-7 weeks; ectopic or not!

What does everyone think I should do?
