How long were you using the bio oil prior to breaking out in the rash? I've been using it for about a week with no problems, however last night I began to notice that I had an itch and this morning I woke up with redness and bumps covering my stomach, chest, back, and arms. I normally don't have sensitive skin but I cannot figure out what else would have caused this rash. It's driving me nuts. I didn't use the oil this morning in fear that it might be what's causing the irritation and will switch to something else if it seems that was the cause of the rash. I'm only 12 weeks and waking up with such a rash (I've never had any sort of skin rash in my life) made me nervous.
