Hai! Lactulose is generally safe during pregnancy, so you don't need to worry on that front, many pregnant mums do take it. That said, a few things to keep in mind: some mums find it causes quite a bit of bloating and gas (which can be uncomfortable when you're already dealing with pregnancy tummy), and if you take too much, it might swing the other way to diarrhea or make you feel a bit dehydrated. My neighbour started on a small dose and increased gradually, which seemed to help her manage better. Since constipation in the first trimester is really common, I'd suggest checking with your doctor or midwife about the right dose for you, they might also have other gentle alternatives if lactulose doesn't sit well with your body. Take care, and I hope you feel better soon!
