Could I be pregnant?

Normally on the mini pill, had intercourse on the 16th of June, missed pill on the 18 and 19th of June. Had what I thought was my period for a few days on the 23rd, everything went along as normal..  Stopped taking the pill at the very end of June. About a week ago I started getting severe stomach pains and then diarrhoea.. Faded away for a few days, stomach cramping came back at full force, can't seem to eat too much without feel sick, increase in urnation, did notice a little bit of light pink blood when I wiped but assumed it was my period starting ( was due on the 16th but has not visited yet) I've noticed a lot of thick mucus-Ey discharge, areoles seem to be slightly darker and nipples are sore to touch.
