Need advice on something!?

My period is a week late I took a test the day after I missed my period and I'm unsure if it's positive or not my boobs are so sore I feel sick and light headed quite a bit and I'm always going toilet and I've got horrible taste in my mouth no matter what I can't go to my doctor for a blood test as they don't do it no more been praying for this baby for what feels like a long time now
