for a few weeks now i have felt sever pressure in my right ribcage. i have a coil fitted and i am bleeding regularly on my period but it feels like i did when i was pregenent with my daughter and she kept kicking in my ribs.. i am really concerned and would like some advice. i have gained 28 pounds in the last 2 months. i have took 5 pregnency tests in the last 3 weeks just in case but they are negative. can a coil make the test negative
