So for the past 2 weeks I have been having some symptoms that COULD be pregnancy but COULD also be AF?

1: some dizziness (not constant-comes out of nowhere)

2: constant headaches

3: my boobs aren’t necessarily sore but do ache here and there (my nipples are sensitive to touch though)

4: nausea at different times of the day (also feel bloated)

5: diarrhea (TMI—SORRY)

6: Last but not least I woke up this morning feeling more than tired

What do you ladies think? Could this be pregnancy or just AF makin her way into town?
