My period is 6 days late. I took a test at 5 days late with fmu and it was negative... I got an iud out late July, went on the pill and then ended up having to stop it half way through last month. So I haven’t been on any bc since then. We’ve used the pull-out method since then (i know, I know not very effective). It’s not abnormal that my period would be late, but should I keep testing? Would a positive come up this late?
