So heart broken and don’t really know what to think 😕

Ladies if you are like me and having a hard time to conceive you know this feeling all to well 😕 I have been trying to conceive with my fiancé for a little over 2 years.. and nothing has happened for us. Last year I was really heavy so I decided that I was going to turn my life around. Last year I weighed about 220 pounds. I worked a lot, I went to the gym and I was on my feet all the time. This passed December I went for a checkup and they weighed me. I am now currently 150 pounds. I don’t smoke, I don’t drink, and i changed my eating habits. I get regular periods every month. I don’t know why I’m not getting pregnant 😕 I’m doing everything the right way and it’s really stressing me out. I sat in my bed two nights ago and had a meltdown because I thought this month was my month. I took a pregnancy test and got a faint line. I wasn’t feeling different which made me believe it could have been it. I woke up Tuesday night with my period. I just want to give up, but I know I can’t. I want a child more than anything in this world and I don’t want to lose faith but I slowly am. Can anyone give me advice, or tips that have helped them get pregnant? Really any advice would really help.
