How far along am I? I’m confused 🤔

My last period was June 2nd, period was “due” July 1st. Today is July 8th July 7th I took pregnancy tests. My periods are all over the place because of being on meds and still breastfeeding my almost 2 year old still… but I’m not really sure…? Why are the test lines so dark if I should be around 5 weeks pregnant..???
