Still no af

I'm a few days late no af, no bfp. But I'm sort of crampy and have waves of nausea. Also my bbs hurt and are heavy that I always have to wear a bra which is a symptom I've never had before. Also I'm super constipated which is also very unlike me I'm trying to eat more fiber or something but idk exactly what will help. I hope this is it finally but at the same time boy do these symptoms stinkkkkk lol. I wanna a little munchkin so bad though and my fiancé is so excited a well fingers crossed
