Hi I just stopped taking my birth control pills september 29 and I would like to know how long will it take me to get pregnant?

Less than a year. 85% of couples get pregnant in the first year of trying - if you're 22 see a fertility specialist (reproductive endocrinology and infertility or rei) if you're not pregnant after a year of unprotected intercourse. See an rei sooner than a year if you have irregular cycles or either of you have known issues - like endometriosis, ovarian surgery, or a history of chlamydia or pid.
TTC. If you and your partner have no fertility problems, and if 22 years is your actual age, your chance is roughly 20% per cycle. This gives around 85-90% chance in one year, though many young women conceive much quicker. Good luck.
