Jazmin • 24 years old - expecting baby number 1. Due date - 10th September 2017
Ok so can I please have some advice? 😞 I posted this yesterday on two pages: 
I typically have 28-32 day cycles apart from since TTC, where my cycles have been super long when I'm stressed. Been checked for fertility problems on my side and I'm all good. I've started taking Fluoxetine last month for depression and anxiety, I'm on cycle day 49 and no AF. On Tuesday I had a small amount of blood when I went to the toilet but NOTHING since. But I keep getting BFN??? What does this mean???
