Do any of you take anything to help keep you regulated?

Soooo.. My stomach "feels fine" I've had so nausea but haven't been sick, my appatite is pretty gone but I force myself to eat alittle here and there(also so I won't get sick) I'm 7weeks 1 day and I realized this morning I can't remeber when I pooped last.. I don't feel constipated but I must be? Are any of u taking anything to keep you regulated ? 
Thanks!
