Having missed 4 days of my birth control pilld my period came two weeks early, I had sex with my husband on day 2 of this period about 3-4 days later started feeling bloated , I put this down to the period cause I was having cramps which felt like period cramps. What I would like to know is could I be pregnant or could this simply be a symptom of my not taking my pills properly? My lower back has been sore all last week as well with occaisional discomfort in my lower abdomen. My mouth has a metalic taste and I have been feeling dizzy on and off.
