Ectopic pregnancy??

Is there anyone who has experienced this.. is it normal to ache and have little cramps now and again and also feeling faint? Did you know you had one by 7 weeks? I had small brown spotting for 2 days when I had bowel movements and it went.. and now it feels like my uterus aches when I have bowel movements 🥴🥴 I don’t know if this is normal or not
