Feeling so down

I have all these pregnancy symptoms  every moth that always turns out just PMS. Feeling like campy, weepy, nouseous shit covered with noticeable veins and acne and then on the top of that getting BFN just makes me want to crawl in the bed and  never get out of it. Now sitting at work and holding my self hard not to cry, no motivations to work or move at all... Can't complain to my friends because all what I get from them is - to stop trying. ( they all have kids)
