my boyfriend and i , we've been having unprotected sex and are trying for a baby . on last monday 1/7/13 he came inside of me multiple times , we figured i would become pregnant , i started having those symptoms : loss of appetite , sleeping continuously , nauseous , headache , back pains , and slight emotional mood swing stages . keep in mind i have never had these symptoms during the times of my menstual cycle in the past , therefore this would not be because of that i'm sure . i was having slight light bleeding which i figured to be implantation bleeding , and which began sometime late lastnight followed by minor cramps that turned into major cramps by 2am or 3am with heavy bleeding throughout the whole day today 1/14/13 , it has decreased to minor suddenly since possibly 4pm . i took a First Response pregnancy test during the Christmas break , and it appeared negative , though i was feeling the same way that i'm feeling now , and i took the second test lastnight sometime with the same negative result , which is very depressing for me . i'm confused and not sure what to think at the moment , i'm trying to keep a positive mindset , especially after dining so much research and noticing that several women around the world are going through the same thing as me , the majority of them have ended up being pregnant . anything is possible , so i'm keeping a positive attitude and hoping for the outcome of being pregnant to be the answer to all of this that is happening . anyone have similar experiences or would like to share their feelings with me ?
