I am 24 and my boyfriend and I have been trying to have a baby for awhile now, recently I have been feeling sick with lower back pain and stomach ache but not like period signs. I have all the symptoms of being pregnant and this month I started to just spot for 3 days and then 3 days ago I finally got my period and it is not like my regular period but it is red in color. Today after only having my period for 3 days which usually last for 7 to 8 days is going away and is lighter in color which is strange to me and never happened before. I feel like I am pregnant because I had and felt these symptoms before when I was pregnant. I took a pregnancy test and it came back positive and then I started to spot so I took one more test and it came back negative, could I be pregnant? I need help to my question, thank you!
