I'm so sorry you are going through this. I'm sending you a big hug.
I had something similar with my 2nd pregnancy. They didn't say it was a ectopic pregnancy, but at 7 weeks, the numbers weren't matching up and the doctors told me that statistically things didn't look good. They watched me with an ultrasound a week for 4 stressful weeks. The numbers didn't improve. The numbers were always 1-2 days shy of where they should've been. Finally the numbers were way delayed.
For me, it ended in miscarriage. I was heartbroken. I hadn't been planning a pregnancy, but had decided I wanted it. I took time off from work. I couldn't believe that GOD would let me go through that. What had I done wrong? The doctors said I had done nothing wrong, but it had to have been something.
Within 4 months I was pregnant again and was able to carry that pregnancy full-term.
What I keep reminding myself is that the miscarriage showed me that I did want another child. You will also be surprised about how many female friends have been through something similar. When I got back to work it was like they were coming out of the woodwork. Most every mom has a story of a troubled pregnancy.
Hugs.
