Weird Cycle

Okay so let me start by saying my doctor cleared me to start TTC #2. Yes I know it’s early.

I had my first son January 27th and bled for 6 and a half weeks. Got one week free from bleeding and immediately got my period for seven days. 9 days later I got my second period that lasted seven days. (Both of those were my periods. Doc confirmed) So 1st cycle was 16 days and now I’m on my second cycle. I got What I thought was IB on cycle day 20 and 22. It was just spotting and old looking blood. Barely enough for a panty liner. Now I’m on cycle day 29 waiting for my period after a BFN. I ordered a Wondfo opk kit, preseed and have been reading up on CM and bbt. Here’s the thing. I have a lot of egg white cervical mucus and I’m on cycle day 29??? What the heck??? My opk hasn’t come in yet so I can’t check to see if I’m ovulating. Is this normal? I’m also Exclusively Breastfeeding my son so I know this will be tricky with weird cycles but the CM is confusing. I thought you only had that at Ovulation? Any insight would be greatly appreciated!
