So me and my fiancé have been trying for 6-7 months. I ovulated the first of April. My next period is do the 15th of April. I added it up and if I am pregnant I was expose to implant some time between yesterday and two days from now. Since my period is a week away I figured the normal period symptoms (bloating at the underwear line, sore and swollen boobs, mood swings) but I am also having nausea and indigestion. And today I went to the bathroom and have a smallish brown streak in the crotch part in my underwear. Could I be pregnant????
