4 weeks cramping normal??

Hailey

I’m 4 weeks and having dull cramping periodically and also dull pain/ache in my vagina on and off ?? It’s not bad but I’m just wondering if it’s normal. I’m also having hot flashes with bouts of nausea. I know the nausea is probably normal but the hot flashes?? I just had an early miscarriage/chemical in November so I’m just an anxious wreck. I had a positive test this morning and my line has gotten darker since 12dpo.
