Early pregnancy and diarrhea

It seems when I get pregnant each time I have a bought of diarrhea consistently for a few days ... I have IBS and other bowel issues so I’m not sure if the hormones are ramping it up or it’s just the nerves? I just assumed I’d always get constipated but it’s always the opposite! I guess if anyone can relate it’d make me feel better . Overall still taking al my vitamins and staying hydrated ... all I can do... i just wonder if it’s a reason to worry!
