Hi there. If you didn't have intercourse, I am very doubtful that you would be pregnant. Even if he fingered you and you suspect precum. Usually it does take intercourse to result in pregnancy.
If you are concerned though, take a home pregnancy test bought for little money at any grocery store or drug store.
Also, periods can be late for a variety of reasons including stress, worry, illness, weight gain or loss, changes in schedule, etc. So, most likely you are just late. good luck
Hello,
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.
Otherwise you can get a serum HCG also done which is more specific than urine pregnancy test.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
