constipation helppppp

Kay
My periods due on the Jan 19th. I ovulated Dec 31. Today (jan 11th) i am still suffering with severe cramps. Last night the cramps were so bad i couldnt lay or stand straight. I took a laxative it didnt work i took another this morning i used the potty 3x this morning but the severe cramps are still there and i havent went again. Could somethingn seriously be wrong? What should I do? My dr is out of town for the week so im asking for ur advice.
