What is going on?!?!?! TMI

Okay my periods are very irregular and irritating. I usually always have my period for 4 days its heavy then gets light and stops. I started the 3rd of this month(saturday) then by the 4th (sunday) night is was gone and was replaced with A LOT of EWCM. Like to the point that i was having to wear a panty liner. It was like i was ovulating. I BD with my husband from Monday to Wednesday then thursday friday and saturday after 2 day period. Then this past sunday out of nowhere i started spotting. And i still am spotting. I dont have to wear anything because the only time i see it is when i wipe. Me and hubby has been trying for 2years this month and its freaking me out. My son will be 10 in april and when i got pregnant it was right after my period. But i have never had any spotting with him. It doesnt make sense but could it be i ovulated monday and now i am having implantation bleeding?
