Ok, I had sex the day after my period ended. A week later my breast swelled, were sensitive to the touch, tender, and my nipples have been erect ever since, my nipples are darker. I'm leaking white fluid that has a sweet taste (bf told me it was) and my breast have been leaking for about a week and a half. My lower back hurts me, I have headaches, cramps. I am 3 days late for my period.
