Trying for baby #2

This is my first month to try for baby #2, so I was curious to see if other moms found the 2nd time easier or harder? My first pregnancy was pure chance/luck, so i am new to the whole "trying" thing. My cycle is around 33 days and I am 28 years old. I have had irregular periods in the past (which is when my first child was conceived), but I have been pretty regular lately, but not ovulating is such a fear of mine bc of the longer cycles.  My obgyn, who is also a friend, told me to have sex every other day after your period until you get a positive sign for ovulation, and then we should have sex every 12 hours for 36 hours. Praying for everyone trying to conceive!!  Would love any words of advice!
