afraid of the disappointment!

So I had my 2nd chemical pregnancy in March. Since then my cycles have been off. I'm 5 days late now and I'm trying not to think too much about it because I ovulated late. I took a pregnancy test this morning and it was abfn. Ya'll I dont know if I can take this anymore! I'm so discouraged. I just want a baby so bad. It's so hard to be late for no reason!!! I've had so many comments this week and last that just broke my heart. One was my uncle. He told me I had some catching up to do with my sister (who is pregnant with her 4th baby.) the other was a patient at work who told me I should be pregnant by now because it's easy if you know your bodies chemically. UMMM NO IT'S NOT!!!! If AF shows up I am going to be a mess. how do some of yall do this for years?? its only been 10 months for us. I feel so weak and helpless.
