period or lack of is out of wack

Vaginosis still no period and I'm two weeks late blood test and reg test rule that out I'm given flagyl which I take until I am down to 4 doses left and I'm having an allergic reaction I  told to stop. Meanwhile I am seeing my gastro for the other pain my Bowles are sluggish but moving I am passing glass and stole so they send me wth some merolax which I take for two days to clear me out and since I am not eating much just a bland diet I don't have much to clear out. Meanwhile I'm still yucky I go

To primary care she runs some test my thyrod is normal my blood chemistry is fine and my liver and kidney functions  are working she sends me for x Ray cuz my stomach is hurting and I have some bloat rules out hernia and I have normal gas patterns. My bp my vitals are all normal. Friday what looks like my period has come it's mostly discharge but very light continues to be light until this morning when the tissue was bright and heavy well this afternoon it's back to being light again. 

I see my primary dr tomorrow for my 6 month follow up (I am diabetic) and I got an apt with my gyno on Friday could this be my period acting weird or something else
