Pregnancy after miscarriage

chloe • 💙💛💚💜❤️

I had a miscarriage on the 1st of July 2017. I was 5/6 weeks along. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is telling me that i am due on my period now but i haven't came on. I did have a few days of slight spotting (more brown then red) last week but nothing since. Me and my boyfriend have been having unprotected sex and he has been 'cumming' in me. When should i do a pregnancy test because obviously i know that my first period after a miscarriage can be strange. Im just afraid it will be a negative. Thanks x
