Unprotected Mishap. 5 weeks PP

May have got lost in the moment and now shitting myself. 5 weeks after C-section and I’ve not used protection forgot all about it, so used to not worrying I am combo feeding so pumping consistently 7-9 times a day. Should I be worried about pregnancy, is that possible this early on? I have no issue with being pregnant but with it being so early I have now thought I’ve had a C-section I don’t think that’s allowed and I don’t know what to do feel abit like an idiot telling my GP don’t know why I didn’t think of this until two days afterwards 🤦‍♀️ From googling no one seems to have done this so early on so now I’m either thinking it’s just not possible to be pregnant or I’m just the only person in the world that’s this stupid and I’m going to split open any day, I’ve had no period so the likelihood is that I’ve not ovulated, so should be fine? Anyone got any experience.
