My husband sleeps in briefs and I sleep naked. I found some sort of sticky substance, reddish brown in color on a small tan pillow I sleep with between my legs. I have no idea what it could be, and am worried my husband may have had a wet dreams and ejaculated through his underwear on me as well or that the pillow could have spread it to me since I had it between my legs. I realize this sounds far fetched but I have severe anxiety over pregnacy and want to know if this possibility is real or not. I can't take any form of birth control unfortunately due to severe side effects, so I'm always worried.
