Is Fatigue And Deep Sleep A Side Effect Of Gildess

Is fatigue and deep sleep a side effect of Gildess birth control? I just started taking it three days ago. The first day wasfine. The day after I was more tired than usual and went to be early. Yesterday I overslept because I didn't hear ANY of my alarms which is unusual if I've gotten the proper amount of sleep for me and I haven't been doing anything more strenuous than usual. Today, the same thing. I missed serval notifications (which are loud) and all three of my alarms. Any insight?
