Asking if I'm pregnant yet

I feel like a failure every single time someone asks me if I'm expecting yet. my husband and I have been trying since April 2016. I had a chemical pregnancy in June 2016 and ever since, I have been super irregular. I haven't had af since September 15th and had what I thought was a faint positive on Friday and now nothing. is there any hope? I avoid seeing my family or his family because they always ask. it hurts me so much, but I don't want them to know we are having problems. does anyone have on advice for the whole family/friends asking? or advice on getting pregnant with irregularity? any over the counter meds?
