Stopped birth control. No period. Negative test. Now spotting.

Alex
Hi. I finished my last pack of birth control about 2 months ago. I had my period during the fourth week of placebo pills as usual. I was supposed to get my period about 2 weeks ago and it never arrived. Pregnancy test was negative. Two days ago I started having light, periodic spotting. I would chalk this up to just my body adjusting but around when my period was due I had intense nausea/motion sickness that has since subsided. I've also been uncharacteristically tired (can't stay awake past 8 or 9pm). Sometimes cramping but hard to tell what's what. Should I take another pregnancy test? See my doctor? Or just wait and see? Thanks for the advice ladies!
