period and conception w/1 tube?

Kori ann

so I got pregnant for the 6th time and at the point where my hcg levels started dropping again. this time on their own, and due to my history of three ectopic pregnancies, my doctor went in to look at my fallopian tubes. long story short, a cyst that couldn't be removed growing THROUGH my left tube. I had that tube removed November 15th. spotted for a few days, but here I am Dec 22nd and still no period. is that normal has anyone experienced a single tube removal and when did you start your period after? Has anyone actually got pregnant with one tube? I am kinda feeling hopeless at this point. anything helps! thanks
