Can I conceive?

I posted this earlier but got 0 responses in hours. May b it's wasn't clear. My period used to be about 3 days long and the flow was medium. Now it has reduced to about 1.5 days hardly and the flow is still medium the first day and hardly anything during the remaining 0.5 day. Does this mean I'm not fit for reproduction? Do you think I can conceive? Do women still conceive when their menstrual cycle is all messed up??
