I am on my day 30 (expected dt 18 apr) and I see only spotting but no blood flow in an otherwise regular cycle of 28 days with normal bleeding and no delay. The spotting looks like gummy brown discharge that can be seen only when I wipe with a tissue and is observed only few times in a day. We are on pregnancy plans so also took preg test yesterday and got negative. Do i need to see a doc immediately ? Note : I had to undergo D&C 2 yrs ago due to elevated thyroid levels, since then my thyroid levels are under control.
