Help!? Water break or sperm

So TMI. Husband and I were dtd and we stopped before anyone finished. We sat there with me sitting over him and after a few mins we felt that the bed was wet. Both of our parts were right where the bed was wet and now we don’t know if he finished and didn’t notice it, if it was pre cum or if my water broke. It was not clumpy or anything and smelled like bleach !
