Hi. We are ttc. I have missed my period by 4-6 days now. Last week Monday I had periodlike cramps with nausea (no vommiting) and a headache which lasted for about 2 hours. Yesterday (Sunday) I again, nausea no vommiting and headache. Today I have a light brown discharge but still no period. My breasts are swoolen, espesially my left breast. I have had periodlike pains for about two days 2 1/2 weeks ago but way too early to be period pains. I recently got a leg cramp during the night whilst sleeping, I NEVER get leg cramps... I took hpt (about 3) a week ago, but all came out negative. Could I be pregnant?
