Is this last one positive? Will I miss our chance?

Al

My partner flys in this afternoon after being away. I believe I just got a positive OPK. I know sperm take 6hrs to reach the egg and for some you’ll ovulate approx 12-24hrs after a positive (for some it’s longer but I have short cycles so I’m probably closer to 12hrs)

Will we will our window of opportunity? :( It’s our last chance for quite a few months! Won’t get a chance to BD until 8:30ish tonight x
