My gf and I had makeout session not even sex at 10 or 12 November but she had some semen in her hand she wiped it in a towel then touched her vagina. That's it. She had periods on November 22 to 27. Filled up 6-7 large pads and after that we didn't had any sexual activities. But on December 15-16 she had light spotting and didn't even fill a pad and till now she didn't had periods. Is there a possibility of pregnancy? And today (3rd January) she had a mild spotting again with a little bit of blood. Please helpe me confirm it. (She has pcod and we didn't had any sexual activities not even makeout after the last session).
