I was spotting a bit, the spotting went heavy, and I was advised to up my folic acid. Each time I took my dose of folic acid, I had bleeding started up every time again for another 6 hours. Then the bleeding would stop, all would be good, and I'd take my dose, and the bleeding would come on again bright and heavy. I looked into it a little, and my diet has high contents of folic acid just because I have a lot of green smoothies and bananas daily. So for now, I'm laying off the folic acid supplements, eating healthy, and I may take one here and there if I don't eat well for a day or two -- once all spotting of any sort have stopped. But I'm no doctor! Just a healthy preggo who's learned to trust nature and super healthy eating.
