Avas~ I'm hoping that is the case. I didn't have implantation bleeding my first time and I have only spotted during my period, never in the middle.
You might have a mild cervical irritation or, sometimes women on the pill spot. Do you still have your package insert for your pills? Read through that and see what it says about spotting.
I actually don't have it anymore, I will look it up online and see if I can find anything. I'm now stressing out.
Dont stress, I know easier said then done! But stressing will make your period late. Just relax and try to think positive.
birth control pills can cause you to spot if your not on the right one for you. Unless you are purposely missing your pills and have done something that would mess them up, (miss pills) then I would say not pregnant.
laura~ I missed one pill but made it up right away when I noticed that I forgot. I looked at the info and it did say it could cause spotting if you miss a pill but I have before and that didnt happen and it also said that if you only miss one pill there is no need for back up prevention, so who knows!
