Okay so basically, I was on the yasmin pill for ages, once one pack ended I started the next pack(I had no breaks, I have low b12 so my doctor advised me to) I got my period on the 26th of September not a bother once I stopped taking yasmin, reason I stoppe was it was effecting my moods badly. I had my period anyway then like a week later I had sex which was protected with a condom. I'm just wondering would I be pretty safe ? I've been getting cramps and my boobs have gotten sore. I missed my first day of my period so is it possible that I could be preg ?
