Has anyone had random bleeding

Mariangely • Mother of baby Ethan James 8/12/17, 30 yrs old, and I`m a proud English teacher👩🏻‍🏫
Im 11w 2d pregnant and last Monday we had a scan and baby was moving about and being happy. But last night a few hours after having sex I bled red on my underwear and when I wiped. I monitored all night and it stopped right away THANK GOD!! But I would like to know if I should call my doctor or wait until my next app on Feb 3😥
