Help!!! TMI

1 day till period. By now I'm have some discharge and spotting. But I have none of either. To the point it's uncomfortable to wipe(from being so dry). Super weird. Been ttc for 14 months. This is our first round of letrozole. Anyone else have this? Had a positive opk on the 11th and terrible ovulation cramps the 13th. Having some symptoms but I know it could be AF also. Trying so hard not to get my hopes up. Took a test yesterday BFN.
