I’m pregnant on depo shot

I can’t believe this I got pregnant 2 months ago in depo and lost the baby!

The doctors assured me to have the next shot and I should not ever happen again it’s so rare

So I did and went on as normal well I have taken another test today and it’s positive again

I can’t believe this I’m devastated I already have 3 children two being 3 and under and I am high risk pregnancy

I don’t want any more children but I hate the thought of termination

I don’t know what to do ?
