Brown and Pink discharge/Pre-ovulation

Hi... i recently had sex with my girlfriend about 5 days ago... the first time we used a condom and when we were done.. i wiped off my penis and went to the restroom to urinate... about an hour and a half later we did it again except with out a condom.. keep in mind i thourghly cleaned my penis... we did it only for 5 minutes with her on top... i didnt come near to ejaculating..and than we stopped and felt the tip for pre-cum but it was dry..... 2 days after she told me she bled a little which started out light red... than turned into a pinkish color... and than to a clear thicker substance... she had not begun her ovulation cycle... she has since started her ovulation cycle 2 days after the light bleeding.. and her period isnt till the end of the month... any reason why she discharged pink... or is it just her ovulation discharge coming out?

Hi. I can only think of a couple of things. The first is that if the sex was a little rough she might have had a small internal abrasion that bleed a bit and healed. The second is that she had a bit of spotting which is not uncommon around ovulation
Hope this helps
