i had diarrhoea too as i love spicy food and sometimes my stomach gets rather weak! i did check in with my gynae, theyd advice you to get meds from GP if it consistently gets in the way (let them know your preg) and drink lots of vit c :)
Yesss i had a bad diarrhea for weeks during early pregnancy and from what i read its normal. Itll get better as weeks goes by. Maybe you can go GP for some medicine.
I had diarrhoea too in my week 4 especially after morning breakfast. I think it’s quite a common first trimester symptom. Do remember to keep hydrated ☺️
it’s normal and won’t affect pregnancy. don’t worry so much
