im 5 days late as of today ive had a headache ive felt sick and ive been exhausted and my boobs are getting darker. Last night i did have sex and today i did check cervix (medium/firm/closed) and tonight ive been having lower pelvic pains and I had a bit of brown discharge it was less than a penny or even a finger tip and my lower back is starting to hurt any ideas ive never had this before?
