Fertility question

I am wanting another baby and on the 25th I had a yellowish discharge and then on the 26th it was clear and stretchy like a egg does this mean I was fertile on the 26th because that is the night we had intercourse

In a normal, healthy cycle cervical mucus would be seen as follows.

Period
Several dry days (no mucus)
Onset of thicker, cloudy, type mucus.
Mucus gradually thins to egg white consistency also increasing in quantity (ideally you should have 5 days or so of clear, stretchy, mucus)
Ovulation
Rapid drying up of mucus

With what you are describing I'm wondering if you actually saw arousal fluid, or if you saw the mucus after you had sex, seminal fluid??  It could also be caused by certain medications or irritations etc.  Really it's hard to get any sort of definitive answer if you are only looking at 2 days of your entire cycle.  If the mucus continued being stretchy etc, I would think ovulation was more likely to have happened several days later.  BUT sperm can live for up to 5 days in good mucus so that might have been enough also.

Good luck!
