Implantation bleeding (sorry may be a little tmi)

Ok so I’m on baby aspirin once a day, 100mg progesterone 2 tablets twice a day, and prenatal vitamins, I started taking all this when my fertile day was approaching. I’m 4 dpo and started to bleed last night, it started out light pink and then went to brown with slight discomfort/cramps in abdomen and lower back and when I woke up this morning it was starting to get redder and slimy (sorry tmi) still with the cramps, it’s not on my pad but there when I wipe and some in the toilet kinda slimy/stringy and other times kinda like tissue particles. I’ve had multiple miscarriages (like 11 or 12) in the past and also have two little girls. But now that my husband and I have started to try again and now that I’m 4 dpo I’m so scared about this bleeding. With my two healthy but high risk pregnancy’s with my little girls I never had any type of implantation bleeding. I guess I’m just hoping that maybe some of you ladies have experienced something similar to this type of implantation bleeding and have had successfully had a healthy baby. Any advice or info would be greatly appreciated. Best wishes to all you lovely ladies who are TTC and have conceived! Baby dust to you all!!!

Oh yea and af isn’t supposed to come until about 7-10 days from now.
