I am trying for baby number two and was sure I was pregnant. My periods are very random. . The last one being about 6 weeks ago very light. My partner and I last tried 19 days ago. Between then and now I had sore nipples for over a week (npw gone). Have had white discharge for last 12 days which has turned brown ish. I have been having cramps fpr last two days in lower tummy hips lower back.. I had a negative test this morning? Could I be testing too early? I am not regular for periods so I cant go by that?
