Last sunday i had unprotected sex. the monday before hand i was late taking my oral contaceptive pill but took it tuesday and continued taking my pills as normal. the day after having the unprotected sex i took the morning after pill just to be on the safe side.

a week on i noticed my lower abdomen is quite hard? i have 5 days left in my current strip of pills . . is it because my period is on its way, i heard the morning after pill may cause it t come early ?

also i have not been passing stools as often as i should. could i be constipated?

are there any other reasons ? i am having no pain.
