Infertility Nerves

I am 25 and should be in the peak of my fertility but sadly I havePCOS. My hubby and I have been TTC for 18 months now. We found out recently the I also have minor hydrosalpinx in both Fallopian tubes. This scares me to death. Risk of ectopic pregnancy is much higher and there is a risk of toxic liquid in my uterus if I do become pregnant. (And a long list of other possible complications) My OB/GYN says it is still safe to try for now but it can get worse with time and she will monitor me closely. I am using Glow for the first time this month and thanks to clomed(spell check?) I have ovulated for the first time in over a year. After ovulation I have to start taking a vaginal suppository of progesterone because my levels were below .5. I know this is a long story but I'm nervous and hopeful and wondering if anyone has been there... If so or even close how long after using glow before your BFP if you got one -- sry if TMI
