Been trying to conceive for about three months now for baby #2. I've been tracking ovulation with OPK and haven't gotten pregnant. The second month of trying to conceive I had a dull throbbing and aches in the lower right side of my pelvis. I figured it was just ovulation. As time went on it became more noticeable and prevents me from sleeping sometimes. But it isn't a sharp pain. More noticeable during menstruation and ovulation. Took a pregnancy test this morning and it was negative.
