So I’ve had light spotting it was brown / light pink for 3 (technically 4 cause yesterday I started spotting again after intercourse but it was for 2 bathroom trips and that was it) days not even enough to fill a pad all together and I had mildish cramps for about 10 minutes while I was sitting it my car. It’s mostly been brown but I kept panty shields on. AF isn’t due for a little less than a week and I have ridiculously painful af cramps w a medium flow. I’m just confused is this implantation??
