Just wondering! Could I be pregnant?

 We have been using condoms, however right in the beginning every time, he sticks it in (LOL) and I have to remind him that we need to be safe. Kind of the heat of the moment thing I guess. However, I am now 12 days late. I keep getting slight cramps which makes me rush to the ladies room searching for Aunt Flo, but she never appears. I haven't tested yet, I'm waiting a few more days - because since I pulled myself off hormonal birth control in April due to bad reactions, my cycle has been a little screwy. I will be late 5-8 days every now and then . But 12! That has me concerned. My periods are usually 4 days long. In august it was 2.5 days and on the light-medium side when I normally have a heavy flow.

Any insight you wonderful ladies have would be wonderful! Thankyou and happy Friday!!
