I need some reassurance, because this is driving me loonie. When I have sex with my girlfriend, I use a spermicidal lube condom and pull out (I come after I'm out). But my girlfriend's period was a few days late, so I started to freak out (even though there weren't any accidents), and she did a pregnancy test. Negative. She was afraid she screwed it up, so we did another. Negative. She was supposed to get her period Sunday, but still nothing. She's been pre-menstrating for the past week or so too, but no blood. I should also probably mention that she told me she missed her period for 3 months one time a year ago. She also recently started sleeping a lot more, and eatting more salad (she started packing her lunches). So I have a few questions for you guys- 1. Should I still be worried about pregnancy? 2. Could she have had her period with no blood? I'm being really paranoid, but I just need some reassurance.
