Pre-Cum / Genital Rubbing she cant be pregnant right?

Hi,
Welcome to ehealthforum,
If you have had urination before sexual contact, chances are that the sperms get flushed off and not be present in pre-cum. If she was during her fertile days during the time of sexual contact, and if pre-cum contained sperms, she can get pregnant. She can consider taking emergency contraceptive within 24-48 hours of the unprotected intercourse to prevent pregnancy. Since these pills contain high hormonal dosages, there can be period and menstrual cycle abnormalities including delay in periods. Avoid further unprotected sexual contact. If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, she should consider visiting her gynecologist to get started on suitable regular birth control measures to be protected (after the periods). She should be regular with birth control use as instructed.
Take care.

I am also facing the same problem.
My bf and I did stuff during my period on Wednesday but we just rubbed our genitals. He ejaculated somewhere else but he had pre-*** during the rubbing. What are the possibilities of getting pregnant this way? The last time he ejaculated was one day before we did (Monday).
I took plan B approx 48 hours after the process just in case. Do i still need to take pregnancy tests?
