When I was on the depo a few years ago it took a year for my period to return and I never got pregnant in all of those months. Not advising you to take any more chances but I think you should be ok. You could always go to the pharmacy in the morning and get the morning after pill if you're worried?! You have 48 hours I think xx
You have up to 120 hours to take emergency contraception but as long as you are within 14 weeks of your last depo you won't need it and can have your repeat injection without problem. Lots of contraception services have walk in and wait appointments. If you can't get an appointment to go by week 14 then abstain or strict condom use.
I've been on the depo Injection since last year. I was due my injection last Monday (15th May 2017) since then myself and my partner have had sex. I've now started to bleed rather heavy and have been getting slight cramps. Is their a chance I could be pregnant?
