Hey I'm new to all of this, but just wondered if anyone has experienced something similar to me. I am now 11 days late , but started using fluoxetine for depression 6 days ago. I have done 4 HPT's and all been negative. Went to the doctors and they took me off fluoxetine as can harm unborn babies. It's not very common but anti depressants have be known to stop periods, has anyone else had this or could I be pregnant? Any advice would be great thanks x
