I am 38yrs, have a 11yr old son, my husband & I have been trying. My last period was March 4th (Start date), 21 days late today. Been having a lot of large acne on my face since period missed, I usually get a few only before I'm due. I have been feeling tired, no sore breasts, lower back pain, feeling full all the time, the last 2-4 days been feeling faint, having headaches recently which is uncommon for me, I am a bit obese, but have had regular periods 28 day cycle. Did have a urine test with my GP on 21st March, which was negative, I think & am hoping I'm pregnant, could I be? Been reading about PCOS which I am worried about, please HELP!
