Strange cycle

Ok so my husband and I just started trying. I had my IUD removed right after my November cycle. We "practiced" quite a bit and I started feeling symptoms. Started my December cycle three days late but it seemed strange how heavy it came on and how quickly it left. Two days of intense heave flow then nothing in the third day   Been three days since and still nothing. But my boobs hurt and my belly button feels weird on the inside.  Just wondering if I should re test or not even waste my time until bext month.
