Confused

Tiffany

Lmp was May 3rd, we only BD on May 20/21. By the 30th I wiped and it was brown and pink. This lasted 2 days. I thought it might be IB but I didn't think everything added up. I've tested and would think I seen a line but wasn't sure when it dried 3 hours later that what I seen was a valid result. My question is with the timing is there any way I could be pregnant?
