According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I've been 8 days late. My boyfriend and i have had unprotected sex 5 times since Dec 22. We've also had protected sex since then. I don't have any pregnancy symptoms but I've never missed a period either. He never came in me when we've done it because he's told me. But one time he almost did.
