My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> is telling me my period is 4 days late .me and my boyfriend have unprotected sex all the time but both nothing usually happens. The other day I was feeling real nauseous, and lightheaded . Should I take a test or wait a few more days I’m very nervous and don’t know what I should do I’ve had a pregnancy scare before but it came back negative
