Chance of getting pregnant?

NOTE: This probably isn’t the right group to add this too but I wasn’t sure which one would be best.

I’m 4 months pp and stopped taking my BC last month because I couldn’t BF any longer and it only works if you’re BF. The doctor canceled my appointment on me to get BC weeks ago and can’t see me till October. We drank and had sex on the 18th and I ovulate tomorrow. I had a full period before this ovulation and now my cervical mucus has been more wet the past couple days. What do you think? Opinions?
