Bleeding after sex

Samantha
My husband and I had sex and when I went to the bathroom there was an alarming amount of blood. After sex I would typically spot/bleed but being 5w2d and my first pregnancy I'm concerned. I read articles saying spotting is normal, but requires more attention if clots and vaginal tissue are being passed, along with very painful cramping. We've chosen to abstain from sex until my appointment(2/24), but I'm just scared that we stupidly causes something to go wrong. I'm still spotting but haven't experienced any cramps. Any similar experiences? What did you ladies do about sex? 
Thank you for reading, just very concerned. 😣
