I'm only 4 weeks pregnant but symptoms I have are swore nipples (normal) but Iv got the worst heart palpitations it sometimes frightening. Iv got pcos and have been on metforformin for about 5 days so maybe it's the tablets or is it a normal symptom so early on. This will be my third pregnancy my last 2 pregnancy I had miscarriaged I know I'm very early on I'm trying not to worry or stress but my heart palpitations have me scared. Hopefully this is a symptom and I'm not going mad lol
