Follow your heart hun. I understand how you feel about not wanting to put ttc on hold. With Gemma it took us over 13 months to conceive and it was with clomid in the end that got me pregnant(oh and Corey of course!LOL). Maternity leave is great, gives you peace of mind, but like you said you might not concieve between now and then but then again you might..........tough choice............sorry I'm not much help!!

ETA should add when we were ttc with gemma I thought I didn't qualify for maternity(did though in the end) but we still were ttc as we didn't want to miss our window
