period returned 2 weeks after c section!

I had a planned c section 2 weeks ago. I had bleeding for the first week and then it completely stopped. Now a week later i have started bleeding heavily again but im convinced its my period! The last few days i have had bouts of diarrhea which i always get before my period. My legs have been achy and iv had period cramps. So it feels alot like a period! Totally different to postpartum bleeding, has anyone else had their period return so soon? (Also i am not breastfeeding)
