Pinkish discharge ?

Ha

So I know it’s tmi but me and s/o will have sex . Then I’ll go to bathroom there’s no pinkish discharge . I go to bed and wake up and there’s pinkish discharge and it’s been like that the last couple days it’s not boood just pink tinge .... I’m concerned I mean I’ve never had a miscarriage and it’s been 4 yrs since my last one and I’m kinda worried . Anyone experience this I’m 6 weeks pregnant almost 7
