I was getting what I thought was my normal AF cramps, about 5 -6 after ovulation and then they went away, is that normal? MY AF isn't scheduled to come until wednesday or thursday of this week. My breast are huge and very very sore and I was running a very small temperation yesterday during the day and I feel fine, but so far this morning my temperature is ok. Very constipated but the pregnancy test I took today came up negative. It could be too early test, right? Can someone tell me ? 1) does implatation cramping come and then go away after a couple of days and 2) Do you think it's too early to test? 3) Am I having pregnancy signs?

Thanks
