opinions please ..

Va

been TTC for about 1 year granted me & my husband have had the ' if it happen it happens ' mindset for about 2 1/2 years .... my cycles have been pretty regular ranging between 28 - 30 day cycles which is normal for me... I'm currently on cycle day 35 which means i'm about 4 days late we did baby dance during my ovulation week & peak day ... ive had sore/ tender nipples, fatigue, nausea, headache, a slight cold, and been emotional / having mood swings... i did take a pregnancy test this morning & it was negative.. would love to hear some opinions on this ...
