You had your period 18 days ago and now appear to have some bleeding again you are usually on a 33 day cycle you have been having symptoms such as sore breasts and nausea. I have only used pullout.pg?

I would say #1 Go to the drugstore and get yourself a home pregnancy test. And no matter what the results,(they have been known to be faulty but only 1 out of 100 tests) then #2 Make an appointment and go see your doctor or visit a local clinic and have another test done professionally. I wouldn't panic yet, you could have some reaction to something, a pelvis infection, or maybe the flu and a growth spurt in your breasts. The the painful nipples is usually a definite sign of early pregnancy. Maybe while at the drugstore grab some condoms for the next time, or baby booties.
