Mid cycle spotting vent 😢

so my husband and i want to try for our second baby. i dont feel like I'll be abe to get pregnant 😢. 2 weeks after my period i started getting what was ovulation spotting we had sex a few times on those days but the spotting only got worse i thought maybe we did it to rough. its been almost a week and i m still spotting lightly. AF is due by the end of the month and i can feel her creeping up on me ... i feel like there's something wrong with me 😢
