First pregnancy only for 4w along. My cramps have been horrible! I keep reading it's normal though. I haven't bled but They have been constant and occasionally I'll get a strong cramp that makes me sweat and curl into a ball. It last 5m or less. Twice I thought about urgent care but I've tested after and still pregnant. My lines are dark. I feel like I'm cramping more than normal and thought maybe it's twins . Also my boobs feel huge and my bra doesnt fit anymore, my lower back is constantly aching too. My friend told me I was feeling a lot symptoms early. Any one had the same experience?
