I started taking the pill (not on the first day of my period) and stupidly had unprotected sex within the first week of being on it. I have continued to take the pill since then, but I'm really worried I could be pregnant. If I wait until the end of the 21 days and then have the week off would bleeding on that week off mean I'm not pregnant? Is the week's bleed an actual period or is it just a bleed? Alternatively, should I stop taking the pill now and wait for my period to come naturally? Any help would be highly appreciated!
