I have been trying to get pregnant

Hi, I'm 25 years old and my husband and I have been trying to get pregnant. I have been diagnosed with PCOS 7 months ago. I haven't had a period for about 8 months now. Two days ago, I saw brown spotting when I wiped. I was super excited because I thought my body was actually trying to start a period. However, I haven't got my period yet. It's just brown spotting in my pad, i have really bad cramps, my lower back hurts, my feet are swollen, my breast are tender and I feel nauseous but have not thrown up. On top pf all that I have been eating EVERYTHING in sight. Could I be pregnant? I pray that God blesses my husband and I with a baby. One of the desires of my heart is to be a mother. If I'm not pregnant I will still praise and give him all the Glory and will adopt a beautiful baby boy or girl...
