Hi all . I'm 7dpo and I've just wondering has anyone experienced what I did last night . I woke up not feeling very good , very weak , dizzy , hot flushes ,heartburn, ringing in my ears . This all lasted for at least 10 mins . I got water into me and all seemed to be ok then . Is this signs or what ? On my first pregnancy I would have got this at the end of my pregnancy when my iron levels were low but not at the start . Any advise greatly appreciated x
