We had intercourse on the 12th, 13th and 14th day of my
cycle. On the 23rd day of my
cycle I started having spotting that was brown, stringy and very
light, though enough to stain my underwear. This spotting was not accompanied by any cramping or bloating, usual menstrual symptoms for me. This lasted until the 24th day, then suddenly stopped. I also had a stuffy nose for those two days that disappeared as quickly as it came, also rare for me.
