So this morning my SO and I took a test it was negative. We BD'd Oct 11th and I ovulated the 14th. I was suppose to get my period yesterday but it didn't come so when I took the test this morning I was spotting. And I went back to the bathroom and now I have this. Is this my period or implation bleeding? I got two BFN. It's lite pink with brownish in it. My period is a lot heavier than this first day first morning
