I'd definitely call my Dr if was you. It is better to go in and get a blood test done than risk harming your baby due to the medications you take. It could also be stress related though. If you are more stressed than usual it can mess with your cycle and cause you to be later or even miss your period all together....Try to relax. Getting a test from your Dr will help that too in my opinion.. Good luck! Let us know how things turn out!!View Thread
