Needing a little fertile window guidance!

Hubs and I canoodled last night and I got my positive ovulation this morning. Instructions say ovulation will happen in 24-48hrs so are we suppose to canoodle again today and tomorrow? I see some only do every other day but I’m new to this! Any suggestions appreciated!!

Also, if anybody knows, will breastfeeding hinder my chance of conception? I still breastfeed my 16-month-old but my period has been pretty regular for 6 months now and I’m ovulating every month. Will breastfeeding cause a miscarriage or prevent pregnancy?
