I've been on NR for years. Always had a heavy flow. I've gained about 30 pounds since july. I replaced my ring on February 17th. Had unprotected sex on the 23rd(coitus interuptous) which we all know isn't 100%. March 9th I removed the ring. A few days later I had a very light brown, pink tinged period. Replaced the ring on time. Now I took out the ring on the 6th. I started this morning with something very similar this morning. Extremely light brown discharge. There was some pink last night. I'm honestly not sure what's going on. HPT was negative. Is this normal or should I be concerned? Possible pregnancy? I've already called my obgyn to try to come in this week. I feel that regardless, I'm going to need a sono to figure out what's going on. Any suggestions/recommendations?!
