Successful 6 week pp check-up, got the okay for sex, and decided to get an iud but until my insurance approves it and my doctor sets up the procedure my OB wants me on the pill, has anybody else gone down this route of pill and then iud? I've looked into it and got a few different stories but I trust you ladies more than the stories others have told me. The particular iud my OB is ordering for me is supposed to stop my periods altogether eventually which will help with my anemia, and it lasts 5 years, she offered the arm implant as an alternative but I've seen firsthand the effects of that on more than one person that I know and I don't want to go down that route. My SO and I have talked about all options and wanting to have another child, he's 100% supportive of whatever birth control method I choose and not rushing me into a second child until we get the hang of things and we strengthen our relationship more (if you've been following me since my early pregnancy he and I have been together for two years now going on three but our relationship got rocky during my pregnancy).
