I came off the pill in June and have had a period exactly the same time every month since. me and my partner had sex on Sunday 3rd December. I was due to start my period on Thursday but haven't come on or started spotting. I have taken 2 pregnancy tests, one on friday and one today both which say negative. I am 3 days late. am I likely to come on my period or could I be pregnant? any advice would help :)
