Is it possible? Help me out. It's bugging me.?

2 weeks before my expected period I had unprotected with my boyfriend three times. We used the pull out method, I am sure he knows exactly when he is a bout to finish up. I was due around Jan. 16 for my period... I had no period... Just a lot of white/clear discharge.. I usually get that before my period but it goes away..But it did not for along time. It was bad to a point where I soaked my boyfriend during [Yes TMI sorry] I still get really wet sometimes. I find it really hard to get comfortable at times... Stomach has been bothering me.. More stomach pains than anything.. Not really cramping. I suddenly got weird Migraines a few times.. bad ones. Never before had. I get nausea form time to time but have not actually vomited.Kind of lightheaded too. I am not really stressing about it at all. It's just really annoying cause I tested myself 4 days after my period and it was negative.... I have another tester.. FIgured I would give it until the beginning of next month to test again? If negative still then go to a doctor? I am confused... I hear stories about women who do not find out until 3 months along etc cause they kept getting negative results. Do you think the odds are high that I am possibly pregnant? The condom did come off once and was inside me but i pulled it out no problem.. He has also d outside my . It's just really confusing. I am old enough to take on a responsibility of a child.. But it's really starting to bug me.. Negative results and all.
