Warning tmi!!!

Ok, you all have been warned. I feel absolutely embarrassed about asking about this. But I'm honestly lost now. Last time I had sex was may 10. Three days after my period ended. Went on through out the month with slight pink cm. it's become quite common for me. Well my period came last month, right on time. June 8th was the first day. Difference was, it lasted 10 days!! It's usually 7-8. So right after it ends. The start of the slight pink discharge.  It's continued ever since then to today. Difference this month, it's actually turned red, and it's just, blobs. Everytime I go to the bathroom. It just comes out. It's the size of a pistachio. It freaked me out this time because it looked like a MC. Going to sound gross, but I happened to have gotten it out(obviously with stuff I threw away) and thank god it wasn't, it's literally a pinkish blob with lots of blood, it doesn't stay together, nor does it break apart. It's not a blood clot cause I have had tons of those since having my daughter. I have been very nauseas, tender breast, headaches, cramps, stomach fullness, I thought it was pms, then ovulation symptoms, but for a month and a half straight, I am beginning to doubt it. By the way, I was giving a steroid near the end of my period. I took pregnancy test last month, and they were negative. I have to search for a doctor, but any ideas what it could be?
