Pop pill!!read description

went on to the progestin only pill last week. I was on day 4 off my cycle when I took it. And stopped taking it altogether on Monday. I got told and have read that sometimes coming off the pill can actually make you ovulate better when you come off it as before i took the pill i think i was having anovulatory cycles. Although I didnt complete a full cycle off the pill do you think it would of effected my body at all with me only taking the pills for about 6 days? I felt so guilty taking them and because I was feeling guilty I was getting migraines and feeling so low in my mood. So I'm just wanting to know if any one knows if it would of affected my body?
