BFN 😥

So I had my D&C on 3.21, ovulated on 4.8, and was so hopeful to be a success story and get pregnant before my first period, but I had a BFN on 4.18 and 4.19, and got my period on 4.20. So bummed. Any encouraging stories or helpful hints? I really want to get pregnant this cycle. It was so easy last time -- only charted two cycles, but now I'm so worried it will take forever. I'll be 37 soon and really wanted two healthy babies before I'm 40.
