DH and I are TTC. I noticed, after DTD, that there were brownish drips stains on the sheets where he had pulled out. Should we be worried? I've read that it can just be from a blood vessel, or from not having ejaculated for a while or from having a little urine in his tubes. Should he get medical attention, and should I now be worried about having this in me? Will this affect a potential pregnancy or my own reproductive health?
