HELP!!!!'

Hi laides, so I took a prego test Tuesday very faint line, someone tweaked on here you can make it out, so taking another one on Monday, here is what I'm feeling , my boobs are sore here and there some days really bad others they feel heavy. My lower tummy feels odd like a pulling feeling and lite cramps. At times it feels like I have to BM but I don't.. I have bad back acne and acne on my boobs.. I'm normally a soda tea drinker but lately all I really want is just ice water and I am not a water drinker just on really hot days. I has miscarrieges last one was in October , I just don't wanna be happy for nothing I'm soo afraid to be happy.. Is this normal feelings that my body is feeling.. Or is it just in my head I feel like I'm going crazy... Please help
