Concerned

Hey ladies!!

My husband and I have been trying for alittle under a year and he recently lost his job so we are not "actively trying" but we are not protecting either. Three days ago o had some blood tinted discharge and read that it could be a sign of implantation. I also had a couple days of light, light spotting when I wiped but nothing I'm use to. My period is usually spot on. If my app says I will get my period on a Thursday, Thursday morning I wake up to a period. On my last cycle I went one more day longer than usual and thought nothing of it. Fast forward to today, I am two days late on my period and show no signs of getting it. I took a first response test this morning and it was negative. I don't believe I am stressed about him loosing his job, but maybe my body is more stressed then me. Any ideas??
