Hello dear I understand your concern Non penetrative sex does not cause pregnancy in your case as you both are on the clothes. Fingering does nit cause pregnancy. To become pregnant, penetrative sexual intercourse with or without ejaculation during the fertile phase of the cycle is required. Pregnancy test will give positive result when your period will delay by the 8-10 days. But as your period is irregular, it is difficult to cont the normal period date. Spotting could be due to hormonal imbalance, stress, premenstrual symptoms. I would suggest to go for blood HCG test after consulting the gynecologist as it is more accurate test and give positive result only 10 days after the intercourse. Avoid stress, take healthy diet, drink plenty of water and do regualr exercise Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
