I would contact out of hours for advice especially if you’re not on any contraception.
I never had a c section but I'm every 3 weeks. I'm really tired like I can't explain how tired but I think it's draining me a bit now. Every 2 is a lot.. I agree with Lesley get it checked out.
I’m going through the same! My boy is 1 in January!! Mines has been very light tho and only lasting a day or so, then coming back a few days later. Are you on anything? Xx
