I had a faint positive line when I took a test yesterday, as it was faint I decided to take another today, it was a different brand as they didn't have the one I used the day before n it came out negative?? HELLA CONFUSED .. I feel preggo, the main giveaway is the heartburn & constipation as I only experience that pregnant, never normally .. also heightened sense of smell n my boobs have swollen but they're not sore?? I dont know if I'm going crazy or what??
