NAUSES

elisa • 26. TTC for the past 8 months
I have been feeling super Nauseas lately throughout the day. Also dizziness. I took a pregnancy test about 2 weeks ago and got a BFN and I haven't taken another since does it make a difference when I take the test? (Like AM OR PM). AF should be here in the next 3-4 days if I'm not. ?
