Spotting please HELP

Im worried :( I am 7weeks pregnant and i was spotting light brown for two days until my ultrasound on my 6w5d. I asked my doctor about spotting but she said that everything looked okey heartbeat was good and sometimes spotting is common.

today i had sex with my husband and after sex i had some pinkish brown discharge.

Can anyone help me? Is my baby okay?!šŸ™
