Bleeding after sex

Last 2 months I've had brown spotting for 3 days a week before AF was due. 
Last night my DH and I fooled around but didn't exactly have sex, bit embarrassing but we didn't have lube and I wasn't wet enough for him to penetrate.
 Any how I woke up at 4am and there was red spotting- nothin since. Do u think that's normal?!
