Period is 1 day late- Need advice

Jessica

As of today (Sunday) I'm 1 day late on my period. I took a test on Friday, Nov. 15 and it was negative. My hubs and I had sex yesterday and when I was cleaning myself there was a tinge color of blood so I figured AF was starting and put a pad on. Since then there hasn't been anything. Not even when I go to wipe after going to the bathroom. I'm scared to take a test. <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> said I should have ovulated on Nov. 2. We're not tracking this cycle since it was driving us CRAZY after trying for 13 months, so we try to have sex at least 3-4 times a week. Has anyone experienced this and got a BFP?
