My period is really light they are usually heavy and very painful moreover there is almost no pain and for the first two days the blood was a deep brown colour but only in small amounts. Also my stomach lately has been making weird grumbling noises even though i am not hungry, also for some random reason I ve been feeling gassey and i have to hold it in when im in public places, sometimes its a little bit painful to hold it in, could this also be the reason why i am easily getting constipated lately? I have other symptoms like small headaches and feeling light headed, or feeling very tired and i sometimes have a sharp pain in my lower back it lasts for like 5-10 minutes though, it only happens once in a while.
