Im so scared 😞

So my period is so irregular... Has any ones <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> been totally wrong.. Like off by a whole week? Its making me really nervous. My period was supposed to start on the 26 and i only have had protected sex since my last period. I had sex 4times this month and each time i used protection. So there is NO way i could be pregnant. We always check to see if the condom broke. No precum or cum has EVER got inside of me. .... So what could be going on? Im really nervous because i can't afford to have a baby rn in my life. Please Help me 😞... Its just weird that it hasent come on yet. Ive only had <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> for about a month now and the last period was pretty accurate. Please comment and tell me what you all think.. Ive also have had this milky white discharge for the last two days.. Any feed back on that?Â
