TMI. Poop??

Victoria • My husband and I had our first baby girl in January 15,2017. Happily married since August 2016.
I am 16weeks pregnant. I'm in desperate need of advice. I'm very constipated it really hurts to poop I just wanna try. I need to poop yes, but it hurts soooo much!! Any advice will be great for relief and easier to poop.
