I had a period on aug18th lasted 7 days had sex a few days after when I should of been ovulated my next period was due sept15-18th it hasn't shown up yet but glow says am ovulating this week. So my question is do I take a test or wait a while longer. I have been having symtoms to my breast have been hurting since a week after I should of ovulated not fuller or darker just hurting. I don't really feel any different yet besides am tired but that's bcuz I work nights so I hardly get any sleep am hoping for baby number two my daughter now is 4 years old and in preschool. So what should I do test or not test or wait a few more days?
