Hi.. I Am A First Time User Of Daphne Pills

Hi.. i am a first time user of daphne pills what should i do if in case i skipped a pill due to failure of seeing the arrows properly. And most of the time i forgot to take it in exact time. Also there's one time i forgot to take this pill. Didn't take another so i just left it unused and skipped to the next. My husband and i had sex in between those times.. i am worried that i may be pregnant but i dont feel any pregnancy symptoms.. i plan to stop taking it as soon as i finish the pack.. and stop using it next month at least ..please advise. Thank you
