I am three weeks late on my period after being off the pill for a month (only took it for a month). have some signs. test n- 1 week ago though. prego?

Off pill ? pregnant: First off - it usually takes at least one cycle of BCP's to be protected against pregnancy and you only took them for a month. With you being 3 weeks late I would be concerned that you are pregnant. another explanation is the pill "messed" with your normal cycle. I would check a first morning urine pregnancy test in about a week. Good luck
