Period starts then stops

Just looking some advice before ringing the doctor if needed. My period was a week late and when it arrived its been super light almost to the point of not being there. I havent had to wear a pad and its only appearing when I pee and its on the toilet paper. Ive been feeling sick and getting headaches along with bloating and stomach feeling weird. Has this happened to anyone else. We have been ttc for awhile now.
