So I am 7 dpo and the past few days I've been having cramping, back aches, acne and my cm has been creamy looking and some days it's a lot. I've had no spotting. I'm hoping this month will be the month with ttc. I'm trying not to stress but it's hard, and reading everyone else posts has me having major baby fever. When do you think I should take a test??
