Okay so me and my boyfriend had sex in the 12th and and my period usually comes in the 18th.. And it still hasn't come on, i don't even know if I have had any pregnancy symptoms.. But I have been going to sleep a lot lately.. My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> on even said wait 5 days and I am soooo eager for it to come on. Will a home pregnancy test work? If it do.. How do I do it?
