I was due to ovulate CD 14, had unprotected sex cd 10, 17, & 21 (protected sex on cd 13). Prediction was that af would show on cd 30. It didn't. I had spotting cd 25-28 (very light pink then brown). So I took a test cd 26 & 27, both were negative. Nothing changed. So again on cd 34 I took a test, negative. I think I may have ovulated cd 21 instead (cycles range from 28-35 days) putting me at a 35 day cycle. I have been experiencing fatigue, nausea, indigestion, night sweats, leg cramps, vivid dreams, tight chest, cold symptoms, itchy stomach, gas & constipation (TMI sorry). These were all symptoms with my first pregnancy but I got a positive right away then. I'm scared to get another negative, any thoughts please?????
