I tested on 9th dpo and was not pregnant .i occasionally have rabeprazole tablet 20mg due to my GERD .ON DAY 10 i did not test ,on day 11 i did not test in morning but had reflux ,so took one tablet. In the evening i got a faint positive ..i just took 1 tablet of rabeprazole at 11 dpo..it says rabeprazole should not be taken during pregnancy..now m panicking..my doctors appointnment is not until 3 days...any one with similar experience??
