Hi Alex, I am 20 weeks pregnant and had some brown spotting about the size of a twenty cent piece in my knickers this morning when I woke up. Haven`t had any bad cramping and no bleeding since. I haven`t had intercourse or any internals recently. I have contacted my obstetricians office to see if I should go in but they have yet to get back to me. I`m a first time mum, probably over paranoid..I hope.
