I have had my period. But it's been late. I've been nauseated and getting sick. I keep having really bad pains in my lower stomach and my lower back (no where near time for my period). I have trouble sleeping at night. I am very moody all the time.. It's getting to a point it's ridiculous. I have head aches. I am weak and tired all the time. also been very constipated. All of these seem like sings of pregnancy but I take tests and they're negative.. anyone ever had this going on? and did you end up actually being pregnant ? My boyfriend and I have been trying since August and no luck yet...
