The day after...

So after an extremely emotional day, yesterday, I am still awaiting my period. I am now freaking out about what could possibly be delaying it. Obviously I am not pregnant, as the blood test so kindly confirmed, so what could be the problem? Brian told me to wait it out and see what happens in the next few days. I just am worried that it is something serious, I used to have irregular periods, but I worked hard to regulate my hormones and get my cycle regular. So far I am on cycle day 32, I haven't had a cycle this long in over 3 years. I don't feel like my period is coming, I don't have cramps, I don't feel bloated, I actually lost 4 lbs last week, my boobs are a tiny bit sore, but not like they were over the weekend. I do have a bit of brown discharge, sorry I know to much information, but not enough to warrant a tampon, pad or even a pantyliner. I even worked out on my elliptical last night, hoping that would get things moving, but no. I think I am going to give it until Wednesday and then I am calling my doctor. I think the worst part is I have no one to talk to, who has any idea what I am going through. Most of my friends have kiddos and the friends that are struggling have a condition that is causing their struggle. I have nothing medically wrong with me or Brian, so I think that is what makes the situation so frustrating. There is nothing wrong to get fixed, so we just keep trying, we keep feeling the disappointment and feeling like failures.
