Hi, I found out on 23rd of January I am pregnant, I have pcos and very irregular periods, my last proper period was 21st October, i then had spotting for a week in December from 3rd-11th, I took a test during this week in December which was negative, my clear blue test the other day said 2-3 weeks which would make me 4/5 weeks but I'm not sure how accurate this is. I've been experiencing the exact same cramp I would get with my period, is this normal?
