TTC emotionally draining

Who would of thought TTC would be such an emotional and mentally draining experience. I am late on my period by around two weeks, my cycles are long but I’ve never been this late, I’ve had symptoms of early pregnancy but negative tests. I am so worried about being told I will not be able to conceive it’s all I want to complete my life. I don’t know what to do maybe it’s still early maybe I didn’t ovulate till way later or maybe I’m fully out but if that’s the case send my period so we can try again. I’m so deflated and upset and worried I just don’t know what to do. I don’t want to give up I want to keep trying but how can I without a new cycle. I’ve not been diagnosed with anything as of yet but since TTC I feel like I’ve noticed my cycles be more muddled than before 😢😢😢😢 me and my boyfriend are trying to keep it a secret that we are TTC because of the added pressure but I may have to tell my sister or someone I feel like I have the weight of the world on my shoulders Glow is the only way I can talk about how I feel about this situation but on anon x
