So i have a question its been almost 2 years since i stop my bc (birth control). I started my period 4 month after i stop with bc and it was going normally till 3 months ago. I was going from every 4 weeks to now 5 weeks. At first when I thought its been 10 days that i missed my period, so I thought i was pregnant but i wasn't. And now my period is missing again which was suppose to start 5 days ago( still not on my period). Its going from every 4 weeks to 5 weeks to now 6 weeks. Its like its adding an extra week to my period every month. I wanna go to a doctor to check it out but I don't have the money for it. Is there anything i can do for this odd adding a extra week period thing? I wanna know if its normal or not?
