Your girlfriend can take a pregnancy test to rule out (or in) pregnancy. Thats the only way you wil; be able to find out what is going on.
How far in to her cycle was she then?
I just want to say one thing first, If you do not want a baby, use both a Birth Control and a condom! The Pull out method doesnt work always, trust me! I became pregnant on it, Whilst I was on the pill, my partner is allergic to condoms, I made him prove it! But its always best to use both if you dont want a baby, or dont have sex.
Anyways... It has been 2 weeks since you had sex I am guess, so a pregnancy test will give her a result to whether she is pregnant or not!
AND the Plan B pill can SERIOUSLY screw up your girl friends body, so it really shouldnt be used as a form of BC or at all really.... Because it can damage her body, and thats probably what caused her to bleed. And Doesnt always prevent pregnancy either!
Buy a test and tell her to take it with First Morning Urine and she will get a result by now
Good Luck
i didnt mean day1-2 of cycle, i meant day 1-2 of the start of our predicament.
All i can suggest is that if you are worried about pregnancy that it would be best to take a home pregnancy test or a blood test at the doctors to confirm.
I would assume that since it was only day 1-2 of her cycle that she would not be pregnant. a woman generally ovulates around day 14 of her cycle so you would need to be having unprotected sex around this time in her cycle for her to fall pregnant. Please note that everyones cycles are different and ovulate on different days. If you are trying to avoid pregnancy you should be using condoms and she should look at going on the pill.
Good Luck
Plan B can really mess up a woman cycle. A pregnancy test should be accurate by now, but it seems like you should be in the clear. You two should probablly figure out a more reiable form of Birth Control becasue withdrawal is not very effective. Best of luck!
