I have questions about Clomid, pcos and pregnancy tests? This is my second time to take clomid i concieved the first time 3 yrs ago, I took it the way your supposed to days 5-9 I waited a couple of weeks felt the morning sickness and breast tenderness and heartburn like my first pregnancy so i took a test, came back negative, so i waited another week thinking it was just too early to show up so i took another one and it came back positive, just to prove myself i took a third and it was positive so i told my husband who was a little sceptical and he wanted me to take yet a fourth so i did and it was negative as was the next one. Im a little confused with this I call the dr. and they just tell me to wait now can clomid cause false positives or could it be because i have pcos?  Its really discouraging.  My emotions are arye.  I had a sonogram 3 weeks after my period and they couldnt tell yet if i was pregnant. my dr said he will up my clomid if i am not pregnant first starting with a progesterine is this a good thing or should i be worried?
