Bleeding after sex 5 weeks PP TMI need advice

Savannah • Happily Married mama to one beautiful baby boy 💙😘

I just gave birth 5 weeks ago to my first baby i had a 2nd degree tear but my stitches are gone and i stopped bleeding about 2 weeks ago i know i was supposed to wait 6 weeks to have sex but my husband came home from work we started kissing and things got heated quickly we did missionary and he wanted to switch postions so when i got up he noticed blood on the bed ( so embarrassing 😩 ) he started freaking out thinking he hurt me but i felt fine and we stopped so basically what im trying to ask is it normal to bleed the first time having sex after giving birth im calling my o.b first thing in the morning its 3am and im trying to convince him im ok he feels horrible like its his fault SORRY FOR THE TMI AND LONG POST
