So constipated !

I haven’t had a BM in almost 4 days and I’m dying. Such bad cramps and pressure...the need to go but can’t. I’ve tried coffee and oatmeal which usually help me. Having lemon water right now. But I need to know what else I can try to help!? I know I can’t take a laxative but it’s getting bad. I’m so uncomfortable and work is getting really hard to do. 😭
