Currently 4 or 5 weeks pregnant ( unsure of dates due to previous miscarriage). I’ve woken up this morning very dizzy and with dots floating in my vision. I feel almost as if I have to concentrate on walking in a straight line. I can also really feel my heart beating almost like when you’ve been exercising. Has anyone else experienced this before? I have contacted the gp as thought better safe than sorry. Please let me know your experiences
