Hi ladies. This is my first round of IUI after a misscairage 6 months ago and the waiting is driving me crazy! Today is 14 days post IUI and 5 days after my last Pregnyl injection. I have been naughty and taking HPTs the last few days. I am getting a very faint positive but may just be the Pregnyl still. Today I started getting a brown discharge and I’m freaking out that it is my period starting (I get brown blood first every cycle). Is it possible for period to start while HPT is still positive or could it be implantation bleeding? Blood test is 4 days away
