Period

I barely bleed when I get my period and it’s super painful. It wasn’t always like this either... before I got pregnant with my daughter I was going to the dr about it but they didn’t even seem to listen to me and just said they don’t do anything unless I haven’t had a period in a long time. Even after I had my daughter I bled for 2 days not heavy either and then stopped. Unlike with my son. I just don’t feel like it’s normal... I don’t even fill a pad during the day when I have my periods. Sometimes it’s just little speckles of like bloody mucusy stuff if that even makes sense 😐😐 it’s been like this for over 2 years now

Any advice? Should I find a new dr?
