I'm 36. I had a Paraguard removed in May and this is second month ttc. I haven't used OPKs or temped yet. I think I'm 8-10 dpo but I'm not certain. AF is due 8/11-8/13. I have a 27-29 day cycle. I'm freaked because when my OB removed the IUD it was a bit stuck and he said, "I'm surprised it worked" which has me paranoid that it wasn't working and I'm just infertile. Could I still get a BFP? Wouldn't implantation have occurred by now?
