Morning, I'm going to call my midwife in a bit to be on the safe side but I just wondered if anyone else has experienced this; I'm currently 25 weeks and when I'm trying to get to sleep my heartbeat slows down and gets quite faint (as you'd expect) but every 10 mins or so it feels like I skip a heartbeat and then get a massive one to make up for it, I can feel a really strong surge of blood up towards my throat and head. My blood pressure is usually at the low end of normal anyway and I take a low dose of aspirin at night before I go to bed, I'm wondering if its that that's causing it and it might be dropping my blood pressure too low or whether this is one of those things that can happen in pregnancy that nobody warns you about?
