TTC newbie!!

Hi all, I'm very new to this all!!! I had my implanon removed 27th march and TTC baby #1, no bleeding since removal of implanon however I have not had regular periods for the last 3 years so not sure when I am due. I noticed EWCM last night before bed and did BD this morning, can anyone help me identify if I would be ovulating?? I have had terrible stomach cramps for the last week, my discharge is very watery and clear today! Sorry TMI any help would be appreciated :) xx
