I have been on the pill for 3 months, with no breaks. In month 3 i missed some pills and was having unprotected sex, so then i didnt bother finishing the 1st pack and left about 10 pills. Its now bin a week since i came off the pill and i havent had a period, what is the chance of me being pregnant and when should i test, because i havent had a period in 3 months
