So me and my fiancee have been trying since September not really keeping track of my fertility days or ovulation.. my period is irregular. Last month I really thought I was pregnant but no.. but now I am keeping track of everything.. but kinda losing hope.. we're never alone except on Friday and Saturday cause my son goes to his dad's then and I don't feel comfortable doing anything with my son around.. is that weird.. lol.. anyway I'm fertile this week today being my highest day.. what should I do???
