<human>: I fooled around with a male friend on July 29, 2015. He rubbed his penis before rubbing my vagina but there was no penetration or ejaculation. I fear that there might have been precum so I took the morning after pill around 26 hours later. I ve had three periods since then, but lighter than usual. Now my period was supposed to come in the past two or three days. What are my chances of being pregnant?
<bot>: HI, I understand your concern.  Firstly you did not have ejaculation/ penetration. Even pre-cum deposited externally on vulva . Can not cause pregnancy.  - You also had taken plan B after 26 hours.  * taking into consideration above things, you do not have a chance to conceive with said sex, * The menstrual irregularity is following plan B consumption (which is a high hormone dose) tends to cause hormonal imbalance & disturbed periods for few months.  Thanks.
