I’m losing my mind

Had sex and it caused bleeding . We didn’t know I was bleeding until we were done and it was on him and on myself . Almost like a light period. We had sex earlier in the day and I didn’t bleed just when I wiped it was very light pink. I feel I caused this and upset that I had sex the second time . Ever since that I’ve been spotting. I can’t do anything cause it’s the weekend and avoiding the ER since the Coronavirus. All I read and hear that red blood is bad and I’m devastated that I’ve miscarried . I’ve been in a slump and just been in bed the past day . Anyone bleed red and was ok after having sex?
