So I was on NuvaRing for about 7-8 months. While I was on it my period was 3-4 days. I came off a little over two months ago. My H and I have had both protected and unprotected sex (he uses the pull-out method when we don't use a condom). The first period I had came a day later than normal, on a Sunday night, and was a very light pink and turned bright red the next day. It wasn't heavy, but wasn't as light as spotting either. It was enough bleeding for about two regular pads. The second day was much lighter, but still enough for maybe one pad. Then by Tuesday night/Wednesday morning there was nothing. No spotting or brown. So a total of two days.
The second period I had, which started yesterday morning at about 4am, came with cramps and again bright red blood. I changed my pad twice yesterday, and today (the second day) it is again much lighter. I am still on my first pad.
What would cause 2 day periods two months in a row?
