Help please?!

Ok my cycle has been on and off since September and it's kinda been annoying since the times I do start bleeding it's when I don't have access to my pads and tampons because I am not at home and am driving somewhere in a family member's car. I started out regular after getting my periods back after having my 2nd child last year in November. Got my period like usual in February March April June and it skipped in May and July and August I just lightly had it almost like spotting really then starting in September it would start then stop and start again with mostly spotting to light bleeding and here and there it would be a lil heavier bleeding like I normally do. It has been like that ever since. I can put screenshots up of my cycles of it would help anyone to tell me if this is normal or not, I also have a photo of the bleeding that started just today while I was driving my mom's car to go pick up my 1st born son from school and got back home right away to use the bathroom so it might be a bit of a TMI photo but still. I am constantly feeling exhausted/tired and nauseated and have been really moody lately and just really irritable at times, also occasionally my breasts feel sore and achy which makes it hard to let my 2nd born son who is almost a year old now but still breastfeeds since he isn't quite weaned from it yet since I was doing the whole child led weening instead of trying to force him to ween off of breastfeeding. I don't know if the breastfeeding still is a cause for all of this or not. I didn't have this problem after my 1st son so I am really confused and need some advice I think. Please help if any of you know anything about this please.
