I have never been on bc before, until last September when I got pregnant, I had miscarried. I then decided to start the pill in December. In the beginning my only side effect was my moodiness and ZERO sex drive. It took a toll on my boyfriend and I. He felt I didn't find him desirable and such wise, and my constant mood swings eventually caused us to break up! It is not May, and I am having CONSTANT random spotting. I had my period 3 weeks ago for about 3 days, then a week ago I spotted for a couple days, and here I am now..... once again spotting!! This inconsistency is SO frustrating!!! I'm thinking about getting off of it! I don't know!!
