Bruises and hairloss

I’m nearly 4m pp and I have got so many bruises and my hair is falling out in huge clumps. I’ve heard the hair thing happens, could the bruise thing be to do with hormones too? I never was one to bruise easily and now I’m covered.

Also extremely tired and drained all the time- I don’t think it’s related to having a baby lol. He sleeps well and I’m well rested in theory…
