Pregnancy with blocked tubes?

Martin
In a nutshell, have blocked tubes, then a procedure to open, then an ectopic that required removal of one tube, then left confirmed blocked again, then IVF cycle of 2 embryos with 1 pregnancy carried full term (yes, I have an almost 3 year old), then frozen Transfer of 2 embryos which was unsuccessful.
​So, is there anyone out there with 1 tube that has blockage that has had a successful pregnancy without assistance?  I am out of money for infertility treatment and looking for some hope!
