Good day girls. I have such a situation. My pulse jumps every day. The tests came out good. The ECG is also good. We did an ultrasound of the mammary glands, it's also good. Doctors don't even say that everything is fine with you. What I wanted to ask is this normal during pregnancy? Someone who has been through it a little bit scared. I take valerian sometimes two, it doesn't help. I take four pills, it's very difficult what can help from there why could it be like that?
