Hysteroaalpingogram (HSG)

I had HSG test today. I also have a laparoscopy on Wednesday because I think I have endometriosis and may be causing the problems of my infertility. i have been TTC for 15 months.                                                   My Fallopian tubes had no blockages. Good sign right? well now i don't know what to do! Should I still have the laparoscopy? Please help!
