Blood pressure keeps dropping

This is my first pregnancy so I’m still learning what is normal or not normal. I’m 6 weeks and 4 days as of today and have been having dizzy spells, and falling over. It’s been so hard to eat with the nausea, but I’ve been keeping up with fluids and eating as much as possible when my stomach feels up to it. I decided to purchase a blood pressure monitor since the app wants me to track it and I had a thought that maybe my BP was giving me issues. I took it the night I bought it. 94 over 70. Today I checked it about two hours apart. First was 85 over 63. Then it was 80 over 59. I did read that pregnancy can cause a drop in BP but it didn’t tell me by how much. Is everything going ok for me and the baby? I’m definitely bringing this up in May when I go for my prenatal visit, but I’m worried something is wrong.
