TTC for 2 years

My husband and I have been trying for 2 years ( I am 23 ).. I have been known to have cysts on my ovaries that can delay my period for weeks...my husband has had all the test and he is fine.. A couple of months ago I finally fell pregnant but with in hours of having it confirmed from my doctor I had a miscarriage. I am now 2 days late for AF and tested negative yesterday :(. I am so scared to test again. And even more scared that its just my cysts playing a joke on me. Anyone else had any luck or advice they can give me on tips and tricks?
