confused, i missed four pills

hi
I'm taking yasmin, I have been taking it for about 2 1/2 years, by acciddent I missed four pills of the end of the first week of the pack. I am usually very good about taking them but it was a busy weekend. Today is a tuesday, I just ended my period not this last sunday but the sunday before. On the day I missed the fourth pill I started bleeding as if i was on my period. it has been about two days of bleeding so far. I have heard yasmin is sensitive to "in between bleeding" especially when you miss pills, but this worries me. Could I be pregnant if I missed a pill and had sex that week before my period? I have not had sex since the week before my period. I have also heard of miscariage stories, or could something just be wrong like an internal infection (I have heard you bleed if you get a kidney infection). I just want to make sure nothing is wrong with me and that all is good. thanks soo much in advance!! very very much appreciated!:)

When you stop taking your pills you can start to ovulate.  Therefore, if you have not had unprotected sex since you missed your pills then you are most likely not pregnant.  

When you miss a pill you usually do start to bleed.  Most likely you are just responding to the missed pills.  I think it'd be close to impossible that you were pregnant.
