So I was getting af on the 16th of this month I noticed I was slightly bleeding only really when I wiped I noticed and now it's 18th and I haven't gotten any big amount it's only when I wipe and I always have VERY heavy periods, could I still be pregnant? I feel sick this morning I'm so confused why I can only see blood when I wipe
