Could I be pregnant? Please help!

Hello, I hope that you ladies can help me on this issue, I’m a becoming concerned. I’m a teenager and my boyfriend and I had sex 2 days ago. He wore a self lubricated condom, and he also pulled out before he came. After we had sex we saw that this weird milky colored substance was pooled on the floor. My boyfriend didn’t cum in me and it didn’t really look like anything that had ever been discharged from my vagina. He felt it and said it didn’t feel like cum/semen. We’re thinking that it was the lube from the condom that pooled on the ground. This morning I had some stomach issues and then I used the bathroom and it immediately passed and hasn’t come back (keeping in mind that I do sometimes have stomach issues in the morning and I just flew in a plane across the country). I was wondering if any of you had experienced this and if you knew what it was. Please help! Thank you!
