My girlfriend and I were having sex and when I took out my penis, there was milky white fluid stuff on my penis and there was also milky white fluid under her vagina. It was not ejaculation because I ejaculated towards the end of the sexual intercourse. She's been having discharges during sexual intercourse over the past few days and it is not fluid, for it is like thick discharge perhaps. From what I learned, these are healthy discharges. And my girlfriend just finished ovulating the past last week. So I believe she just came out of ovulation that is why she is having discharges and now she has this milky white fluid discharge that was around my penis and under her vagina near her butt (note it was not my ejaculation). I need help? Is this normal? Is it safe?

She is not pregnant as well. She got her period and she just finished ovulation last week. So I want to know if this is okay.

Thank you.
