Wtf ovaries!

steffanie • 29, ttc for the first time. I`m into video games, reading, tv and general malarkey
So my avg cycle is 34 days. Been testing with OPKs since cd 18. Finally got strong positive today on cycle day 25. In April I had a 41 day cycle but last month it was 28. Do I have a good shot if I have sex over the next few days? Will my body have enough days left for the luteal phase?
