I had sex 1day before my furtile date & 5 days before ovulation so my chances of becoming pregnant are 20-25% is that high?

No. . This doesn'take sense. If you had sex 5 days before ovulation then how did you have sex one day before your fertile day? And if they were two different sex events and neither is during a fertile period then i think the chances are more like 0 to 5 %. I'd be curious to know how you came up with 25%. Basically you need to have sex within 3 days of ovulation to have a shot at getting pregnant.
