I've been with my husband for a yr. and 8 months. We've had intercourse various times(recently all unprotected, we are both checked n no kind of std so we had no worries) but just yesterday after intercourse which I figured was just wet I noticed it had a real light red tone to it . comes out to be blood. Its the 1st time this ever happens. All I've read is it can be I had torn or pregnant but idk what to believe Is it normal or what can be the cause?
