Two and 1/2 weeks ago I missed my period for the first time in my life. I am 29 on BCP and have FMS. I know it is unlikey to become pregnant on Birth Contol, but it can happen and I have all the symptoms. My question is to all you brave ladies that have had children after your FMS was diagnosed. I know that sometimes our biochemistry can be skewed by the condition and meds. Has anyone been pregnant and not been able to detect it right away with a urine test?
