am I going to get pregnant?

If you're reading this, please answer to the best of your ability I really want to see what a lot of you say. We never pull out during period. On the 15th and 16th after my period my bf and I had sex without pulling out. On the 18th, he did pull out but says he felt like he did it a little late, that he was already cumming as he pulled out. We aren't trying to prevent (obviously) but aren't really trying either. We're just tending to pull out around fertile week. Today I had a thick jelly-like cloudy blob come out in the bathroom. I'm not sure my exact ovulation day, but what are my chances of a baby here?
