It's possible, but not terribly likely. However, you should use birth control of some kind from now on if you don't want to have another baby in 10 months or so. Although it is rare to be able to get pregnant that quickly, it does happen. Breastfeeding doesn't always stop ovulation.

I want to make sure I understand your post correctly: you said that you found that it IS or did you find out that it IS NOT recommended 2 weeks after pregnancy.

Sex is not okay usually until after 6 weeks after pregnancy. No doctor will ok you for sex at 2 weeks. With the amount of pain associated with recovery and the exhaustion you experience from delivery and the care of a new baby, I do not understand how you could be having sex in the first place already.

You need to heal after the delivery, avoid infection, and it also allows time for your hormone levels to go down again so that you do not immediately become pregnant, because this can definitely happen with hormone levels the way they are after you deliver.

If you think you pregnant, you will need immediate medical attention and will have to have a lot of care for the duration of the pregnancy. Either way, do get checked by a doctor to make sure that no harm has been done by having sex that early, and make sure you get your pap smear at 2 months postpartum as long as your bleeding as stopped.
