Not sure if I asked

So almost 6yrs I gave birth to a beautiful baby girl I had a very complicated birth including she almost came 3months early due to a tear in the sac a piece of my placenta got stuck after my daughter was born plus when she was about two months old had my gallbladder and stones removed also had an infection which is clear can that may be a reason of being hard to have another one most say it's cause of weight but big girls and smaller girls can get pregnant with no problem but also the same ones have problem with irregular period so I wanted to ask or c what you all think I will definitely be talking to my ob when I go to my appointment
