Bleeding gums while brushing?

I haven't been brushing like i should be lately due to a lot of stress and anxiety killing my motivation to do anything. Brushed for maybe the first time in 3 weeks last night (gross i know) and my gums bled slightly from 2 or 3 different spots. In the past while neglecting brushing It has happened but only between the gap of my 2 front upper teeth, this time is was this spot and 2 others. Brushed again before bed, bled again ( a small trickle from front teeth and less in the other spots) Brushed in the morning and there was less bleeding maybe because i was extra careful brushing and did it softly and slow. Brushed after work and less blood still but can still see it if i apply tissue to my gums to check and I can slightly taste it. I know its probably gingivitis due to poor oral hygene as they do not bleed when im not brushing, but still worry about other things seeing as I've had some random bruising in the past month although I haven't had any new ones in a week and currently bruise free. Noticed blood in stool 2 days ago and occasionally a very small amount on toilet paper. but by the way I explained it to a GP he said it wasn't concerning. Thinking about getting blood work done, had CBC 4 weeks ago which all came back in normal levels, but was that too long ago?
