Hi,hope You Are Great By God's Grace. I Got A

hi,hope you are great by God's grace. i got a 3months injectable contraceptive on 6 july and had my period in july,august and september. i had sex on the day i was supposed to renew it which was 6 october and stated using condoms on 7 october so on. i havent had my period yet and my breasts are tender and of late i had watery mucus which was later followed by creamy type. is there a possibilty that i might be pregnant since i did not renew? sorry i do not have money i thought it wz for free i guess wil try next time bt i really needed help from you people. stay blessed
