horrible cramps, urge to push?

Adirea

My entire life i've never had bad period cramps . they were always light enough to cause me some discomfort but nothing two ibuprofen couldn't fix . now i've been TTC for a few months and it seems like now that i'm ttc my cramps have gotten significantly worse . i started my period yesterday and i'm still barely bleeding , i usually use a super but i haven't even filled up a regular yet , but i was curled over in pain with cramps, i took 4 ibuprofen, used the heating pad, and tried to go to sleep but nothing has helped . the most odd thing about this period is that i have a constant urge to push , like i have to poop. this has never happened to me and this is by far the worst menstrual pain i've ever experienced . anyone else experience the same thing ??
