11 weeks on Friday and I'm in alot of pain

I have been pregnant once before and never dealt with this before. Really bad cramps to the point it feels like I have sharp throbbing pain in my lower stomach and a stabbing feeling in my vag, I have no energy, my legs feel heavy , bad breakouts ( and I never break out, maybe a blemish but not this bad) my breast dont hurt and I have a pounding headache. I try to drink water I do , but even not being pregnant water makes me nauseous, I very rarely drink it. I'm drowsy and irritable. And yes I know having a baby is alot of work I have done it before . I'm just looking for answers on the pain and headaches. Any comments or opinions please write below. Thank you so much!
