I'm having anxiety about people asking me when we will have a baby

AB
I've been trying over 6 months and have not been on any birth control in over 8 years.  I always used the pull out method until my husband and I started ttc.  We haven't been successful yet and if I'm not pregnant by July my doctor will be sending us to an RE.  I'm a hairstylist and I see about 35 clients a week.  I'd say about half ask if I'm pregnant or if I'm trying.  I've only told three people I'm ttc because I had a feeling I was going to have issues.  I started my period Saturday and I full on broke down.  We had a funeral to go to for my husband's grandmother and here I was barely able to hold it together.  When I get my period I get overwhelmed with sadness and then I look at my schedule for work and I see the clients that I know will say something.  It's getting really hard not to break down and cry if they ask or make a comment about my clock is ticking.  I don't know what to do.
