Hi there, I track my ovulation schedule regularly and my husband and I had uunprotected intercourse multiple times per day for four days during this time. It is now 2 weeks later and I am experiencing increased hunger, extreme lack of energy, headaches, milky white discharge and my nipples are constantly semi-erect. All of these symptoms are uncommon for me, especially the nipples. My at home test is negative, what should I do? What else could be happening?
