Lucrin Depot 3.75ml

Hey guys,

I needed some help and perhaps some insight regarding this injection. So I've had a shot at the 10th of May of 3.75ml Lucrin Depot. And had my period on the same month from the 13th to 18th. My doctor gave me this because I am about to get a laproscopy for my choc cyst. Now what I would like to know that does AF get delayed when this injection he gets administered. Because my husband and I was intimate on the 18th of last month which was also the last day of my AF and havent been together since. My period is now 11 days late and I took two preganacy tests which were both negative. And from last night I noticed some cloud thick like discharge when I was cleaning myself in the loo. I just need some info regarding this because I dont to have a baby now. Is it the injection which is causing the delay in AF? Please any insight would be appreciated
