salih on "20 weeks spotting /intercourse"

I am 20 weeks preg, and not to be graphic, but I put intercourse in the title line because I didn't know how else to title the post, my husband and I I guess you would say fooled around, didn't have intercourse because I was scared, but he I hope this is ok to say, fingered me and I had an orgasm. After, I went to the bathroom, and wiped and it was light pink. Is that ok? What caused it to be pink and was it ok to have an orgasm? I hope this post is not too graphic. Thanks
