Insanely embarrassing

Ever since I had my daughter about a month ago my muscles aren't as strong as they use to be down there. Now whenever I go poop it gets stuck.. I'm extremely constipated and I'm taking colace for it but every time I go it gets stuck while trying to come out and my incision isn't completely healed yet so it hurts like crazy. Any tips on how to make it come out easier? Like I said I'm taking colace I tried milk of magnesia and I do kegals. HELP!
