When should we actively TTC?

I'm 28 and I recently stopped taking BC pills and have since returned to having a regular cycle (30 days in length with 2 OPK confirmed ovulations). It would be ideal for me to have a maternity leave starting in March or April because of work duties. This would mean that it would be ideal for me to conceive in June or July. I should be ovulating within the next week or so. Knowing that it can take time to conceive (and obviously could a very long time) would you start trying this month even if it would be a little less than ideal for work scheduling if it stuck? Or wait until the middle of June when I ovulate? We're excited and want to start trying but also want to try to make it convenient (yes, I realize it could take longer and I shouldn't count on convenience). I'm losing my patience on continuing to wait!! What would you do?
