I was suppose to start my period on the 14th and I didn't start until the 20th and it was brownish discharge for the first day and then went to a normal period for 5 days straight then I stopped bleeding for only 4 days and started bleeding again but it was light for 4 days and I stopped bleeding last night around 6 so today I didn't expect to bleed at all but I started spotting very lightly around 1pm and I have no clue what is going on I've been nauseous lately along with very tired and I keep getting light headed can someone please help me and tell me what's going on.
