Discharge in pregnancy?

in early pregnancy(like 4-5weeks) what is the discharge like? coz i have stretchy clump of clear discharge? its like what i get when i ovulate but it was a bigger clump(sorry tmi). i do not know if i am pregnant yet i was just wondering coz i was on the pill and i had my period on the 26th jan. i went back on after my 7 day break but finished after 3 days coz of side effects. this caused me to have breakthrough bleeding. i was due yesterday but nothing. any ideas?
