Aunt Flo is about 6 days late, but when I test I just keep getting a bfn. My last period was on the 29th of October when I stopped my birth control that I had been on for about two months. Before that I was on the shot for 6 months. I only had sex once during my fertile period, the 16th and we used a condom but it broke. I think I ovulated on the 18th but I'm not really sure. My breasts are tender but they have been since i stopped the BC. I've been a little fatigued and I've had like a lot of discharge. Is there a chance I'm pregnant or could it be something else? When should I test again to be sure?
