Doubling Betta no sac!

Gleisy

I’m going through a hurtful and emotional situation and I need someone to share their story with me.. I’m about 4 weeks pregnant with an hcg at 5,300 and in 3 ultrasounds nothing has been found. I have no bleeding or pain except for minor aches here and there .. they wanted me to take the methotrexate shot and I refused, I decided to wait 2 more days . I know some people say I’m crazy but I just need to be sure. The doctors said that even if I was early they should see something with that beta. I’m lost, completely confused . And to top it off just realized I have a swollen nipple which I don’t know if it’s related! Anyone had anything similar happen?
