I have been ttc for 9 months now & still nothing. This is the second month me & my partner been using pressed for 2 months now. Me and my sisters cycle usually come at the same time or a few days apart,  didn't happen this month. My period is suppose to come on today 6/12, and it never came & my period is always a day or two early. I don't wanna tell anyone because I been trying for so long I don't wanna be disappointed. Should I test today or wait a couple for days? I've been cramping but usually my knees lock up also when my period is coming.
