9 days late

Whitney

Okay so I'm 9 days late I took 2 different tests this morning with FMU and they both were negative but my nips are super sensitive I get really nauseous in the morning and I had a bit of spotting last Saturday but that's it. Nothing else. We baby danced the day before and day of ovulation and I'm still getting all negatives.... What should I do anyone have any idea what's possibly going on?
