Hi 
How are you doing ?
Let me start by saying that you can surely get pregnant,nearly every lady will have small fibroids & minimal 
endometriosis. 
Fibroids need treatment only if you have a symptom like excessive blleding in periods , pain , swelling in legs or blocking 
urinary tract. 
Endometriosis is a progressive disease,  & only absolute treatment is stop periods, best method is 10 month of no periods due to pregnancy!!.
Cysts are due to fibroids & also due to endometriosis.
Go through the checklist of investigations & have it done if missed. 
Husband- 
Semen analysis at least 2-  done 4 weeks apart preferably in an 
infertility center ( examination done by andrologist), Blood sugars
Wife - Blood Sugars, 
Thyroid profile          
Ultrasound scans to evaluate 
Uterus , Ovaries & adnexa
          Confirm tubal patency- most important- Tube is the connection 
          between uterus & ovaries( the bridge where sperm meets the egg & 
          forms a baby) this is size of hair follicle & cannot be seen on scans.
           So check with HSG( Xray with dye), or SSG ( Scan with dye) or 
           Laparoscopy
If all this done & found normal , nothing can stop a pregnancy with God's will
At this young age you have a very bright chance & never lose hope , pray well.
If fibroid is protruding into the uterus it will need removal. 
Hope I have clarified your queries
Do write back if any more queries
All the best
