cd32 brown spotting no bfp

Today I'm cd32 I ovulated cd15 tracked with clear blue advanced digital ovulation kit. BD like crazy from cd8. 3rd month ttc been in BCP for ~6 years. Used pre-seed as well and have been taking prenatal vitamins. I started spotting yesterday cd31 it was reddish when I whipped along with lots of EWCM and later that afternoon it was brown with creamy cm. Nothing in my liner. Today same brown tinge with ewcm, nothing in liner. AF was due yesterday. No signs of it as I usually get cramps right when it's gonna start. Been moody and constipated like crazy. Extremely tired like this is so frustrating. Bfn yesterday. I'm scared to test again as I can handle af coming rather than a bfn. I've heard some women not getting their bfp until a week or so late for af. Any advice ???
