Irregular ovulation!

My husband and I have been ttc for two months now and while I know this isn't a long time- it feels frustrating because my ovulation seems to be all over the place. The first month I ovulated right on time in the middle name of my cycle and this month it's been three weeks since my period and I still haven't. Glow has given up making predictions at this point! It's harder because my husband travels a lot for work and so we have to try and be together exactly at the right time and now I have no idea when I could ovulate. I think as a result what I really didn't want to happen has happened which is that sex has become sort of a job and the fun has gone out of it a bit. I think my own stress about being 32 and feeling like we need to conceive baby #1 ASAP is adding to my feeling of frustration. Anyone else having problems with these issues?
