The headache could be because of thr haze too. Was experiencing bad headache when i spot the whole day, i sleep to recover, try to avoid medications. Glad that your your old symptoms are all in control 😊 i have alot of dreams too at the start. Some ppl have it till the end of pregnancy. It's normal. My gynea says too.
Jiayou!! All will be worth it as soon as you see your baby
