Two weeks ago I had sex for 4 days in a row unprotected.He did cone inside of me.  On that last sex day my period was suppose to come according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. In the past 6 to 7 months, <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> has been pretty accurate predicting my period except for my last one. It was a day late.  My period usually lasts 8 days but that time it only lasted 5 days. After my period was over, I have been having pregnancy symptoms,  not sure if it's because I'm so anxious about it,  due to finding out I was pregnant at 7 months my last pregnancy. I took a test and it was negative.  Last night after a 3 hour flight,  2 weeks after last having sex and 1 week off my period there was an unusual mucus in my liner (picture posted). Not sure what to think of it. Help please!?! Oh and according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I'm ovulating today.
