I am nearly 4 days late on my period which is not normal. This is our first month TTC so I did not know to track ovulation and temp. I have not been on anything other than condoms for 5years and always very careful. I'm 4days late on my period, why. Why is my body messing with me like this! I did a first response test and it came up a BFN. I dunno what's going on. I have not been stressed or anything.
