I had my period on July 27 which was the first day till July 2 then I ovulated well I'm prtyyy sure I did. I had sex with my husband during that time and now I started bleeding again which started on July 21 but it seems to be like mixed with mucus but still has a red color to it but now has lightened up and is not as heavy as when it started. I took 2 pregnancy tests but they were the one with the dropper and says on the box early detction as early as 1 day so that really doesn't help. So I need to know what this is
