Okay, I'm 18. I have unprotected sex but my period has never ever been late. I haven't had a period since Nov 23. Yes, the day after thanksgiving. I have all the symptoms, sore breasts, bloated stomach, constipation, fatigue, peeing all the time, veins showing up on my feet, thighs, boobs and stomach. I was feeling nausated but that has subsided a little bit. I eat more. I've gained 2 pounds in the past 2 weeks. I know that doesn't sound like much but I'm only 108 lbs. And I'm 5'2 so, it shows. I've took countless HPTs and they all came back negative. And I just got a blood test done last week and thats negative but I still feel pregnant. Is something wrong with me? If I am, I should be 11 weeks and 3 days pregnant today. Is that possible that I still am pregnant? Oh yeah, I'm still taking prenatal pills just in case. But has anyone been in the same situation and had a baby? Please help, I feel like I'm losing my mind!!
