What Causes Delayed Periods After Aborting An Ectopic Pregnancy?

Hi, I am getting confused as I went to two Gynaecologist and they told me two different things. I am always late on my period about 37 days, last year I had an ectopic pregnancy and I got a shot to stop the pregnancy. The results of testing showed that I have Polycystic ovaries; for that reason, one of the doctors prescribed me Diana 35, also my testosterone levels are a bit higher, everything else on my blood work looks good. Now my second doctor says I dont need to take those pills as he knows that I can get pregnant. I dont know what shoud I do! Help please
