So I I use the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> period trackers and it’s always right. Last month my period started on the 4 and ends on the 9th and the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> tracker said I should expect my period on the 1st and it’s the 8th so currently 8 days late and I still have no period. When I have sex me and my fiancé go Into it without protection like starting the vibe and then we put protection on and always use protection. I took three test and it say negative. I have been taking vitamins and probiotics the pass 4 days. Can anyone help me and tell me what I should do.
