2nd pregnancy implantation bleeding

Anyone have implantation bleeding that was a heavy flow and bad cramps the second time around? I have a 15 mo old son and I know I had implantation bleeding when I was pregnant with him but I cannot even remember the flow of it I just remember the confusion at the time, but I had bleeding that was similar to a period 2almost3 weeks ago that was a week after my period was suppose to be but it was darker and heavier and the cramps were just a different type if that makes sense, and I have been incredibly hormonal and up and down eating everything in my path, my office which I didn’t think smelled is now revolting and food smells just make me gag, a lot of the same kind of symptoms I had last time and am so incredibly exhausted even when I get rest. The big symptom I’m missing though is that my boobs/nipples aren’t sore to the touch like they were with the first one. So I don’t know if I’m imagining things or not. I took a pregnancy test on Sunday the 17th and it was negative. Now I have one app that Is saying my period will be next week and another that says it will be 2weeks from now, and I am freaking out! I just want to know already!

How different were your symptoms from baby to baby, how soon did you get a positive, and how was your implantation bleeding!?

I’m losing my mind here!
