Anyone else think it’s funny the acronym for this method is FAM? No, just me? Anyway...

I got my Mirena out last month. I’ve NEVER been able to handle birth control so I’m not sure why I thought that an IUD would work any better. We have two babies, 14 months and almost 3 years old. They’re 19 months apart (by total surprise). We haven’t decided if we’re done or not, so also not being that aware. I am trying to see where my body’s at with cycles and was using old ovulation tests. I never got a true positive, though I did run out this week, but had fertile mucuous and the start of lines on the tests as of Friday. We had unprotected sex yesterday and used withdrawal this morning. Generally speaking, should i be super concerned about getting pregnant? I don’t think I’ve ovulated yet.
