Confused, any help??

Lisa • Lucky in Love ❤️
It's 4 weeks after D&C ... Started light spotting 2 days ago (brown) .. Pink/red this morning egg white cm.. Stupidly did a test yesterday and there was the lightest positive .. Did it again this morning and a definite positive but very faint.. I'm so confused!!!! Is my body still hanging on to hormone after 4 weeks????? Or is it scarily possible it's a real positive?! 
Think I'll be booking in with doctor today to check my levels, not something they have followed up on and I just need to know where I'm at before I drive myself potty!! :( 
Thanks x
