12 weeks pregnant and so constipated

I have taken 3 laxatives over the course of 4 days and some suppositories. I haven’t pooped more than the tiniest Little Rock’s in over a week. Usually 1 dulcolax works if I really have to take something I am at a loss and very uncomfortable. Any natural remedies or tricks ?? I should mention I drink atleast 40oz a water a day usually more and take a probiotic already.
