Help? Sorry so long!

Okay so my husband and I have tried these past few months to get pregnant. In the past I’ve had irregular periods but with the past few months they’ve been regular, down to the day. I have multiple apps for my period just because of irregular ones in the past. So we did our thing throughout the days that all the apps suggested. I even did the legs in the air thing this time (I know there’s no evidence to say it works but what does it hurt to try?) well I eventually said screw it im gonna start working on getting in shape and forget even about trying, if it happens it happens. Well my apps now say I’m between 7 days and 3 days late for my period. I’ve taken tests that were obviously negative, but this one from this morning has me stumped. I can see a vvvvvvvfl but I know blue dye tests are notorious for this. The past few cycles my boobs have HURT, like to the point of almost tears for a week before I start, plus I cramp yet this time around nothing. I crave things a week before my period and I haven’t had cravings like usual. I’ve been a little emotional, and tired. All last week I needed a nap around 4pm because I just couldn’t stay awake anymore. I, as habit, always check my toilet paper when I wipe and I noticed discharge so I checked it with more toilet paper and it was almost egg white type, but it was thin instead of thick.
