I went on the pill a week after finishing my period and didn't know for the first week you're supposed to use another contraception such as condoms for the first 7 days, me and my boyfriend went straight in and had unprotected sex. I have been on the pill before and came off and had a period a couple days later, but thats not the case this time. Could i be pregnant? If so can i test now? Its been 4 days and i'm in my most fertile period now with ovulation due tomorrow
