I have missed 2 periods now had lots of hpt's all negative, bloods negative as well, my p.h. has been 8.5... I also took clomid 200mg day 4-8 0f cycle before unprescribed could this have caused a problem? Or could I still be pregnant? I have had symptoms & do have 3 children already, thanks for any helpful answers in advance

Many reasons to miss period, if you took blood test after 15 days of missed period and it is negative, then you would not be pregnant from the previous month.

This medication can cause all types of issues if not taken properly, never do so without doctors instructions
