Irregular after IUD removal

Michelle

I had my IUD removed in october been ttc since then. Before I had an IUD I was regular, my doctor said it should go back to normal. My period has been late for three months and each month it gets later. I have had BFN each month. Last month I was 5 days late about 12 dop. So this month I'm now 16dpo and no AF also having BFN.

Something I should worry about or let my doctor know about. Getting frustrated with the BFN because Im always so late and it gets me excited.
