Newbie! Pregnancy worry.

Hi all!

I’m 21 and I just recently became sexually active for the first time ever. Me and my partner have been together for roughly 2 years, and when we have sex we always make sure we use protection as I am not on any form of birth control (so afraid of the side effects). I consider myself a newbie in the sex world, simply because there are still things that I am learning about my body during sex. Just recently, me and my partner had sex about 2 days before my predicted ovulation date—using protection of course. It was amazing! However when he pulled out I saw him quickly panic and turn on a light to wipe something white off his hands. I didn’t think too much of it until I went to the bathroom and seen a milky white substance in my panties. I panicked and immediately went to him and asked if the condom teared at all. He got the condom and we both inspected it very closely. No holes or tears, he even squeezed it to ensure there were no tears and that semen would not come out. We both concluded that the white substance had to have been me. No tears, no leaks, and he always pulls out as quickly as he can before he ejaculates to ensure more caution. It only is worrying me because (not only do i have anxiety lol) but usually i don’t have any discharge or at least that much while we have sex. I also learned that microtears in condoms is a possibility, but I feel that we would’ve noticed that when he squeezed the condom because semen would’ve came out of the tears. Just seeking a bit of reassurance that i have nothing to worry about right now! So sorry if this is a silly question lmfao
