Ttc - cycles different after early mc?

[Ready4Rainbow]

I had a m/c at almost 7weeks the first week of February. I have an 18m old son. Prior to the m/c my cycles were always regular and predictable both before and after I had him. I've had two periods since my m/c right on time and we are ttc this cycle for our rainbow. I've had odd pms symptoms the last two months - really sore boobs, a little colostrum, late cycle ewcm. This cycle I had ewcm cd12, absolutely horrible right ovary cramps on cd14. I have tons of cm and now left ovary cramps on cd16. I am so confused. I know it is too early for implantation or pregnancy symptoms, but Im pretty positive I already ovulated - or I dont know what the cramps were two days ago - they were unbearable.
