if i were you and it isn't a financial hardship i would go to the doctor both to confirm whether you are pregnant or not as well as to discuss what other possible caused could be. i know that stress or other life changes have affected me inthe past but not for 3 weeks.
i am going on 3 wks late on my period. taken 3 otc pregnancy tests. could i still be preg or what else could be cause? . should i get in to see my gyn? the 3 preg tests were taken a week apart but still not pregnant.
