Please help!

I have cyst every month before and after ovulation.. I have also had 2 miscarriages and 1 ectopic pregnancy, but 2 successful pregnancies before them . Also My weight is up and down for the pass 3 years . I just thought it was stress .. I also been depressed alot but i just thought it was because i cant stay pregnant😔 . Someone said i may have pcos because i have very positive lh test throughout my cycle. Does it sound like i have it ? Or am i just overwhelmed because of my history with pregnancies?
