Cramping for about 5 days

I think I'm out this month.😣  I was so sure I was in too. I swear I saw vvf lines but then yesterday they all came up negative I'm due for my period in 3 days(?) or so and I've had cramping for the past 5 days. My boobs have been sore though since ovulation day and I have had some nausea but I have the acne, cramping, and I just feel I'm out this month. Does anybody have any hope they can send my way regarding cramping they may have had before they got their BFP? How long did you have cramping? When did it start?
