Trying to recover from Birth Control

So I got off of birth control about 3 1/2 months ago. I have not had a single period since.

Because of this, I cannot tell if/when I have ovulated or when I will have my period.

However, a few days ago, I saw like a drop of spotting. Then I had the same thing happen a couple days later.

I also had some cramping, dizziness, fatigue, moodiness, and nasea.

I don't know if this means I am regulating or pregnant. At this point, although I am TTC, I would be perfectly fine with a period because at least then I could start tracking.

Has anyone had something similar to this happen to them and if so, were you pregnant or did you end up having your period?
