I went off the pill for about a month, my fiance and I had unprotected sex 2 weeks ago then the next day I got my period which lasted a week (7 days) when my period ended I went back on the pill (after being off it for a month), a week after being on the pill I bleed for just one day, my breasts are more fuller adn tender, I have had headaches and fatigue the last week. Could I be pregnant or is it just the pill playing up? (i am not on the pill at the moment just in case I am pregnant, I don't want to hurt the baby).

If I am pregnant, i'd only be 2 weeks along (from when I concieved) is it too early to take a test?

I feel a bit silly not knowing weather or not i'm pregnant coz I have a 15 month old already, but all pregnancies are different aren't they? Thanks for your help. :)
