Ok so half of my pregnancy I’ve had every symptom already except sleepiness like I wouldn’t sleep during the day like that just the normal night sleep and it wouldn’t be excessive. But yesterday and today I feel very drowsy I been sleeping all day and night and still feel sleepy. I’m 23 weeks on Friday is that normal ? Or it can be caused by something else ? I feel like I haven’t slept for days I can barely keep my eyes open only wake up to eat.
