😞 help

So I had my period in the beginning of January & my calendar says I was supposed to come on Sunday & here it is Tuesday & still no period. Idk what to do. I'm sure that I'm pregnant, but right now life is too stressful & money is tight. Plus I just had a baby 5 months ago. *Don't judge* I'm just so numb right now. It's so much going on idk what to do.Â
