I had a D&C March 1st, and have been having sex through out the month with the okay with my OB. He told me I should start my period between 3-4 weeks after D&C.. which was March 29th. I have taken 3 pregnancy tests every other day since the 29th and each one has came up negative. My last test was taken yesterday morning. As of today I have very LITTLE brown when i wipe mixed with clearish stingy discharge. Was curious if this more likely to my period trying to arrive or possible pregnancy?

Advice would be lovely!
