So I was on the Nuva Ring for two months after having my second baby and I was having bad side effects so I switched to Microgesterin. I have only been on it for one month, but I spotted every single day until three days before my period. I was supposed to get my period six days ago and I haven't. I only spotted one morning during the week I was supposed to have my period. I have been on birth control many times and have never had this happen. Is it just because the hormone change from the Nuva Ring to the pill? I took a pregnancy test a couple days ago and it came back negative. Any thoughts on this would be great!!!! Thanks.
