i went to sleep last night and i was perfectly fine, i woke up to a splitting headache, really bad stomach ache and i cant get rid of the feeling that i'm going to vomit. when i try to vomit i burp, and i have just been to the toilet so i know i'm not constipated. Also every now and then i feel faint, i have some water and it wears off. but i constantly have this migraine and stomach ache and the feeling of needing to vomit. im not pregnant as im on the implant and im on my period. lately i have been having my periods more frequent than usual and they're heavy periods so i don't know if it that whats causing it but i just really want to know because i dont like feeling like this... its terrible.
