I had period pains and lower back pains for a week but no sign of my period. I did my test when I was a week late (5 weeks pregnant) but I didn't get any symptoms until after about 6 weeks, and then I had sickness, sore boobs, a strange metallic taste in my mouth and severe tiredness.
This is only my first month off the pill so it's unlikely I am. I was just wondering for future reference and wondering about different people's experiences.
