Hello!! I just recently got off the pill, so my cycles have not been regular at all. They have been anywhere between 25 days and 28 days. I am not sure exactly when I ovulated this cycle, but I am having major cramps, lasting for several days. Could this be a sign of implantation? We've been trying for a positive pregnancy test for a few months now, but no luck so far. Has anyone else ever experienced these types of pains mid cycle??
