I'm 18 and i've JUST started having sex. I've done the deed 3 times and I've done all this research about fertility detection, rhythm method, and effectiveness of condoms and the pill. I've been on the pill for 2 years for acne reason and I've used a condom every session without slippage or breakage. I try to refrain from the days I'm supposed to be most fertile, or having sex the week before ovulation for example. But all information is different. I hear sperm can last from 5 to 7 days but then I hear 2 - 3 days: which is it?!

My mum's a public health nurse and she's always said that condoms dont always work: does that mean if they slip or break? I've been really careful about my pill lately, making sure I take it every day but the times aren't always consistent: it's usually between 8am and 3pm. I also take zoloft for other reasons: does that ruin the effectiveness of the pill?? My significant other and I also use withdrawl every time: but using the condom and pill as well I still worry lol but is there still a chance I could become pregnant. I'm prety confident for taking all these extra precautions, but I would still like to know if that's ok.
