Senokot Forte

Hello, i’m 15 weeks and 6 days today. I have been experiencing difficulty pooping for almost 3 weeks now. I have urge to poop but it’s not passing through dahil matigas yung poop. I used suppository twice n para mka poop lang. Para syang stone like na poop. I’m already drinking 2-3 liters of water and eating ripe papaya. Nag reseta si doc ng senokot since hindi nag work sakin yung lactulose na every other day. Is it safe to take senokot and gaano katagal kayong nag take nito bago naging normal yung poop nyo ulit? ayoko kasi sana maging dependent sa gamot ei. Salamat po sa advice, first time mom here.
