Chemical pregnancy or still pregnant??

Hey all! I need some input or your experiences! First off, I am 6 months pp, breastfeeding, and not using any kind of bc. My cycles are all over the place but I can usually track my ovulation. I haven't tracked it for the last month or so so I have no idea how many DPO (days past ovulation) I am! That being said, for the past couple weeks, I have been having hot flashes, heartburn, changes in taste, etc. Exactly a week ago I felt like I should take a test and it was in fact very faintly positive (to expert eyes only 😉)! I was not late or anything, just took a test. But then a few hours later, I started bleeding bright red. Heavy enough for me to think it might have been a chemical, but not heavy enough for me to have wear a pad. No cramping, just some vaginal stabs like I had my whole last pregnancy. Bled bright red for 3 and a half day with some small stringy clots. Thought that was it. So that was a week ago. A few days ago, I had a sharp stab in my left side (actual side, not abdomen or pelvis) that I had to breathe through. Weird. But I'm still having hot flashes, changes in taste, increase in vaginal discharge, cravings for healthy food (I'm a donut kind of girl), and this weird achy full feeling in my pelvis. I did take another test the night I started bleeding and it was negative, but I did take it at 8pm and I drink lots of water so it was very diluted. So brief recap: Wasn't late. Faint positive. Bright red bleeding for 4 days that didnt soak a pad. No cramps. And preg symptoms. I think i am going to take a test in the morning. My question is, does this sound like i had a chemical or has someone been through this and still was pregnant? I will attach a picture of my very first test.
