Hi Hun

Try not to worry too much, i have had a few c-sections now, and found that after the ones i had closest together, that i had alot of discomfort, and soreness all the way through to varying degrees, and my OBYGN told me it is because they have to cut not only muscles, but nerves etc too when having the c-section, so they do take a fair while to heal and repair,,,so if you have another pregnancy fairly close,,, you can get a bit of soreness from that
I am sure your bub is nestled in nicely, and it is just your body readjusting to pregnancy once more.
Best of luck with your new little bundle on the way
