curious....

Has anyone gotten pregnant right after their period. I had my period June 12-14 very light period. Had sex on the 16th. Now I have a cramping period is gonna start feeling, (TMI) diarrhea for days, and a little bloated feeling. Which is weird because obviously I'm not due to start for awhile. I also just had a baby that's almost 3 months old. Does that interfere or change when you ovulate?? Because with my other kids I ovulated right around CD14. Just curious if this has happened to any of you ladies?! Thanks!
