vaginapagina | Menstrual consistency (Reply)

Hello my wise friends! :)

I have a question on the consistency of periods. When I say consistency I mean how watery or thick. This is my second period off of birth control. Third if you count the one at the end of the pill pack. Last month was right on time, but I was going through twice the amount of tampons! My flow prior to HBC was usually light to medium and had clots/ lining. On HBC is was usually light to light/medium. I would have some consistency (thickness), but no major clotting. This period is beginning the same as last month. Its on time, but its so thin! Its bright, bright red and watery. No clots, nothing resembling any other period I've had. What is going on? It seems like I am just bleeding fresh. There hasn't been any brownish, "old-blood" coloration. Should I be worried? I guess since the timing of my periods has been exactly how it has always been (28 days on or off HBC) I'm surprised by this. Also, I was on HBC to help with migraines. Last month no headaches. This month I got nasty nausea in the morning yesterday and today. Today I feel the edges of a migraine coming on. Im hoping the migraine will decide not to stay.
Oh and for reference, I am not on any type of HBC, just barrier methods for now. I thought my body was adjusted after how smoothly last month seemed. Was I being silly to think that since I was on HBC for 6 years?

Thanks for your help!
