Bleeding after sex! Help!

ruby
Hi ladies, I am bleeding after sex and its freaking me out! I had a MC which ended a week ago. I was 5 weeks. I miscarried naturally and we have started trying again. But I had bright red bleeding after the first time (1 day after my bleeding stopped) and then nothing the second time and then again last night (6 days after my bleeding stopped) I had some spotting. Do you think it's just left over after the MC or should I be worried? I have never had anything like this before my MC and have always been regular. Has anyone else had anything like this before?
