When to BD...

So yesterday around 5:30 PM I took an ovulation test and it was negative, but close to surge. My husband and I had sex last night around 8:30 (Glow predicted a 27% chance on pregnancy). This morning at 7:00 A.M., I took another ovulation test and got a FLAMING positive. Was our timing good, then? Or, were we too early? Just wondering if we should do it tonight also (although we won’t be home together for another 12 hours, so hopefully we won’t be too late if so). Glow shows a 33% chance tonight, but I’m not sure if doing it tonight would be overkill. We also had sex Sunday night when Glow showed a 15% chance. This is our first month TTC, so any suggestions are welcome!
