Okay. According to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> I was suppose to start AF yesterday. Well I didn't I'm a day late. I've taking pregnancy test like 6-5 days before my AF was suppose to start and they kept coming out negative. Is there a possible chance that I'm pregnant,and it's just to early to read on a test?
