My pack is over at the end of this week and i have been experiencing spotting for about 2/3 days now and I have quite heavy spotting today ( I think my period may be starting) Im on ortho tricyclin lo, its the 21 day pack where i take no pills for seven days after the pack is over. This is my second month on it,i had light spotting a day or two before my pack was over last month. Is it normal for this to happen on my second month this early before my pack is over and this heavily? Its heavy enough that i will probably have to wear a tampon to bed. My pack won't be over for another 4 days. Could I be pregnant?( Ive been having unprotected sex) Should I go to my doctor?
