Missed period

TH
After I had an awesome January with my first period in a while, she went MIA again this month. I went ahead and started my third round of clomid Friday, after I took a hpt and got a bfn. I can help but feel discouraged. I've never wanted my period to stick around so much. But in order to keep track of everything I need it. I never would of imagined it would be this difficult or depressing. I have an appointment next Monday with an OBGYN that specializes in infertility, so hopefully I'll get more answers with her than with my reg dr. It's times like this I wish my mom was still here to ask questions and lean on. Thankful I have my sister and MIL but it's still not the same. Sorry just venting.
