In need of some advice !!

I’m 3 days late , we’ve been trying to conceive for 4 months, I also came off the injection 5 months ago . I’ve only had 3 periods in that time. I’m normally regular like clockwork , but I tested negative yesterday and today . Could I be pregnant, or just late . I want to be pregnant so bad . I’m so tired but can’t sleep , hungry all the time , peeing all the time , especially at night , sore breasts. And I cried over pork chops 2 days ago , my mood is all over the place. Can anyone advise or clarify for me !?? Can’t speak to my sister or mum cause they don’t know and won’t support me . Feel very lonely as a woman. 🥺🫶🏻 thank you in advance, google just gets my hopes up , this is my last hope of getting some real answers. xx

I did this test 6 days ago , it looks like to me a faint line then it disappeared after like 5 minutes. Then all the other tests have been negative. Was it just an evaporation line ??
