not the same

Its been 4years since I gave birth to my angel but every since then my body has not been the same. I tend to have more issues with my stomach. I cramp sometimes for no reason. I feel bloated or alot of pressure like twice a week. Its always near my tubes. Then sometimes I have light pink discharge in between my periods. I don't have insurance so I can't afford to go to the doctor. I swear I have had these problems until after my pregnancy. Has anyone been thru this? Also a year after I had her I went to the ER and they said I had PID but no STD. Then when I went to my follow up my doctor said he don't think I ever had PID. Anyone with a similar story but you turned out health and ok.
