I know this isnt pregnancy related (sorta) but any of you mamas get pregnant with an irregular period? Im ttc now and my cycles have always been spot on but now since im ttc, its been irregular. Like i have 3 day periods instead if the usual 6 days and i started bleeding on the 5th of july when i just had a period on the 21st of june. I dont even know if i ivulate anymore! Please tell me something to help regulate my period or at least when to test with opk. I need something here!!
