Hi I'm 20 years old and my husband and I have been trying for several months now. Just when I think we finally did it I'm getting cramps and a light very light blood. I've always had an irregular period.My last was August 3 and according to my average rate I'm 4 days late. I keep testing every month and always comes back negative and in like a week I get it. Yesterday I had like a milky very watery discharge I've never had before. Should I test or try again?
