I had unprotected sex in the wee hours on the 14th. According to my tracker my peak ovulation day was the 13th. I wasn't trying to get pregnant but it happened this way. I had brown spotting the 26th through the 28th but still no period. I'm nauseous every morning to the point I puke my guts up. Certain smells make me sick. I can't drink coffee like I used to. I'm having shortness of breath. Sore boobs with small veins. Mild stomach cramps and lower backaches. I even started craving weird things recently. My emotions are a roller coaster. I took a test May 5th midday and at first I thought it was negative so I threw it away. A little bit later something kept telling me to dig it out and look at it so I finally did and I seen a very faint blue line. I showed my friend and she seen it right away. The next morning I took another test and I seen a very faint pink line. My friend seen it. I took a test today (the 7th) and I got a negative. They were all different tests but I'm confused. Somebody help?
