Pregnancy brain is real everyone.

So im 13 weeks pregnant. I heard before i was pregnant that u get a pregnancy brain which means u tend to forget shit and don’t remember anything and its true! I was laying here in bed thinking about my birthday and I literally forgot for 5 mins how old was i🤦🏻‍♀️🥺😳😔😫 I thought i was 26 already but im 25 and going to be 26 in August. Also earlier i was talking to my brother about something and i didnt even know what we were talking about cuz we got off topic and started to talk about something else and i was like”what are we talking about it?” 😫 am i losing it? Lol is this normal because i feel like a zombie and im like half asleep . Also couple days ago maybe a week ago i woke up and forgot what year we were in 😂😭😭😭😭😭😭 im going crazyyyyyyyyyy
