One <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> tells me I was suppose to get my period on the 17th, making me 5 days late, then the other app tells me I’m suppose to get my period on the 19th making me 3 days late .. either way I’m late. I know I been stressed lately but my boobs are sore asf , I’m tired 😴 got nausea. So question is should I test at my one week? But when is my one week? And If negative and still haven’t gotten my period test at my two weeks ? I just want it to come if it’s coming goshhh 🙄😩
