Trying for #2

L

Had my first the beginning of January and going to start trying for our second. I’ve always heard it’s harder/takes a while after your first. Any pointers? Advice? Back to OPKs, but think I started tracking too late this month and may have missed my peak. Was always ovulating smack dab in the middle of my cycle (like cd16) but I think I peaked on cd12 or 13 this month?? Possible? Period was always very regular before my first baby. Has been regular now that my period started again, however was a few days late last month (wasn’t preg, was using protection).
