Constipation anyone!?

Erika • Being four...there`s nothing I love more
Hi! I'm over 23 weeks and I hadn't had this before in my pregnancy! I was feeling bloated and heavy and I suddenly realize I don't remember when was the last time I actually went...(if you know what I mean) 
Any suggestions? Things I could take? I'd love to start by trying something natural first but I'm ready to move to plan B if this continues!!! Please help! 😳🚽
