Could I please get some advice? cycle was due 3/21. I'm normally always 28 days. on the 20th I took a test, bfn. haven't tested since because I go to my dr tomorrow for a check up and figured since I was there she could test me if it hadn't shown up. Hubby was finally feeling frisky last night so we dtd. I also exercised a bit harder playing raquetball for the 1st time yesterday. I went to the bathroom a few mins ago and I have pink blood. picture in comments. thank you.
