A worried woman

Alanna
I've been taking some anti-depressant meds and they went up 10mg for my dose. 
<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> has been telling me I am 16/17 days late with my period. Tried talking to my doctor no help. I took a pregnancy test and it said negative.
Any helpful insite?
