My boyfriend and I have been trying for a baby for a month now and I have been having strange symptoms: bloating, abdominal cramps, lower back pain, headaches, nausea, cravings... today I noticed smells were bothering me more than they normally do. I have taken 3 pregnancy tests and they are negative and I have been taking prenatal vitamins for a month. I noticed today when I went to the bathroom I have brown spotting when I wipe. Any ideas?? My period is suppose to start in 5/6 days.
