My boy friend thinks I'm pregnant .. I'm 4 days late , my nipples have otter darker and today I finally seen I was spotting very lightly , I've been very emotional & i have body aches . 
I don't always feel sick and my sleeping has falling off ; im either really tired or I can't sleep. I took a test 3 days ago it came out negative . But I took it while I was at work in the bathroom so I only gave it 10 mins to show me anything . My mother took the same test and we waited for a second line and didn't see another line for the next 30 mins . 
If I am pregnant he wants me to keep his baby but I don't think I'm ready . 
I'm 18 and I just got first apartment & I like my job lol.... What should I do 😒😒😒😒😒😒😒😒😒😒😒
