I am 34 years old. My husband and I have been ttc for 2 years now. My period is always super regular and I am never late, maybe one day early. I was supposed to start my period today but have only slight spotting...its a very light brown and not even enough for a liner. I tested at 10dpo and negative. I tested yesterday at 13dpo and negative....my boobs have been itchy and my back hurts. Slight cramping like my period may be coming but not like normal. Is it still possible given the spotting on my period due date that I could still be pregnant this time?? Please help!
