If pregnant how long will it take for your period tp stop?

If you have sex while on your period, It won't stop. It takes your body time to acknoledge your pregnant. You may slow down to spotting. If you are pregnant, your next month's cycle will not be appearing. Although I spotted one day around the time I should of got my period when I was pregnant with my second son. A little spotting is normal, although I would suggest talking with a ob-gyn. I hope this was helpful.
