Xulane patch with Odd symptoms

Lauren
I just started the Xulane patch on Wednesday the 17th cycle day 1 of my period and I am now on cycle day 6 and I can barely keep my eyes open. I am so tired and am having very bad cramps at the end of my period. My husband and I were TTC but after numerous attempts we gave up and said we would try again later. Last fertile window we tried but I received my period. My cycles are very irregular so I never actually know when my period will start so the doctor said I should get on BC to try and regulate my cycle so I can get a better understanding. Could these cramps and very tiredness be a symptom of the patch? Something is off and I am not sure! Any advice from you lovely ladies would be greatly appreciated!😘
