HELP. I have had many AF problems due to endo. Finally with the help from a homeopathy doc I got back on track and for the past 5 months I have had the same cycle. Every 4 weeks Fri I'd bleed for about 1hour NO PAIN at all. Then Mon. I would bleed heavily and have SEVERE cramping, last about 3-4 days. Well dh and I started REALLY trying to concieve and this month fri came and went monday came and went. I am having no sig. pain that would lead me to belive I am getting AF. I am 6(4) days late (depending which day you count from) and the first HPT I took (EPT CERTAINTY) the digital readout said NOT PREGNANT, the stick, after removal, had a dark line and a faint line...thought maybe it was diffrent so I went and bought the Old fashion POAS kind, (First Response) and took it twice... both NEGATIVE!!! Yesterday I notice blood in my urine and started to get pain so I am drinkin' cranb. and taking pro-bio. I read that UTI can't effect HPT results???? I am going crazy!!!!!! .any suggestions????
