I have a question . I got the depo provera shot yesterday and had unprotected sex today. I know they say to wait 7 days after the start of your period, partially to insure your not pregnant before but I just had my son 6 weeks ago so I know I'm not pregnant and with breastfeeding it takes up to 9 months to get your period again so I just got the shot whenever. My question is, is there a chance I could be pregnant with having sex the day after getting the shot if I know there was no possible chance of pregnancy before. Would anyone recommend getting the plan b pill. TIA
