AF almost 5 days late.

Took a FRER this morning and BFN. Symptoms are very tired, nipples super sensitive, breasts themselves are tender but not horrible, some nausea last night, cm is very creamy and cervix is so high I can't reach it and acne. I rarely ever get acne. Temps are above coverline but barely. Oh and Im super bloated. Should I go to ER for a blood test? My hubby thinks I should just wait it out but Im a little anxious as I had a mc back april. I was only a few weeks along. We have only been ttc for 4 months. My cycles are 28-30 days. I haven't been stressed at all this month. Please feel free to list any advice or encouragement. It is much needed and respected.
