Any advice?

SM • Wife 💑 Child of God 🙌 Dog mom 🐶 2 babies in Heaven 8/2017 & 4/2018 👼👼

So I had AF Feb 19th-23rd, then I waited until the Tuesday before AF was scheduled in March (20th) to test, AF was due Friday (23rd) I got a negative on a Frer and that night I had some dark blood so I figured AF had started. This continued through the 23rd but it was never heavy enough to fill a tampon. So Saturday the 24th on a whim I took a pregnancy test and got a faint line, I waited until the next morning and took one on FMU and got a positive. I went Easter Sunday to have bloodwork done and my Hcg was 238 so they set up an ultrasound for the Wednesday (April 4th) they didn't do a ultrasound because they thought I was too early but did bloodwork and my Hcg had increased to 815. Yesterday I had a ultrasound and the tech was unable to find anything. They told us they were doing more blood work and that we should prepare for the possibility of an ectopic or eventual miscarriage. They called us and said my hcg is now 2755 and we go back for another ultrasound today but if they don't see anything they are going to assume it's ectopic and terminate the pregnancy. The nurse did say that my levels suggest I'm about 5-6 weeks pregnant not the 7 I think I am. Does anyone have any advice? We are thinking of getting a second opinion because of how easily they are ruling this ectopic. I've already had one and this pregnancy is so different from my last. I don't know what to do or think at this point.
