it depends on your body but you might not be prego
Pregnancy occurs only during the time of ovulation. Ovulation is the release of a single, mature egg from a follicle that developed in the ovary. It usually occurs regularly, around day 14 of a 28-day menstrual cycle. Moreover pregnancy can occur only when a sperm fuses with an ova or egg. For this the sperms need to be ejaculated inside the vagina or there should be entry of sperms inside the vagina which travel through the cervix and uterus to reach the egg in the fallopian tube. Chances of pregnancy are less in your case as pregnancy does not occur after fingering.
If you are apprehensive regarding the status of your pregnancy you can get it checked. Most home pregnancy tests that check urine beta-HCG are sensitive to 20-25 mIU/ml of HCG. The test can be positive anywhere from about 2-3 days prior to a missed menses to 4-5 days after, but usually it should be done 7-10 days past your missed period.
