Need some advice

Rose
Me and my hubby are trying for baby last 2 years, we did almost test including HSG and all are normal. But still we are not getting good news:(
My doctor advised me to go for laparoscopy but I am scared to go for it.
I have only problem with my period is, starting of my period I have only spotting for 2 to 4 days than slowly start my period. 
And ovulation pain for one day during ovulation.
Pl give me some advice should I go for laparoscopy and endometriosis.
