19 and TTC 2nd baby

Married going on a year and already have a beautiful 8 month old son. The first little guy was not expected at all and defiantly came as a surprise. However everything went smoothly and he is such a blessing! Now we are excited to actually "try" this time around, however me and my hubby are both very new to this. I just now got my period back from my first pregnancy 3 month ago and my cycles are slowly going back to normal. It has gone 48 days then 38 days so I hoping this cycle goes back to my regular 28 days. I'm clueless on how to track your cycle but I am slowly learning just from reading all the post! This is our first month actually trying for a baby. We have just been doing the deed every other day this month and thought that would be good enough🙈 we shall wait and see!!😂 out of a Normal 28 day cycle, on what day do most women ovulate????
