possibly pregnant

hi, so I think I might possibly be pregnant. I have all the symptoms. sore/tender boobs, mood swings one moment I'm mad the next I'm in tears, cramps, acid reflux feeling, constantly feeling sick to my stomach, achey back, having to pee every 30-60 minutes and I'm always tired. everything started about a week ago. period is due today. I've had very light brown spotting. this would be my 5th pregnancy. my 4th ended in a miscarriage 2 months ago. and I feel like I'm making myself think I'm pregnant cause I wanted another baby very much. but I'm also scared that I am pregnant, cause I am worried that I'll lose another baby. cause the cramps remind me of the miscarriage.

every pregnancy I didn't get a positive till I was about 6 weeks. so for now I'm scared and I'm excited and really worried all at once. and I think I just need something positive right now cause my mood swings have caused me to take my anger on my boyfriend so we've done nothing but fight since yesterday so I'm alone with this. I just can't stop my mind with all the crazy horrible thoughts.
