Hey guys!
So,  i ovulated on March 3rd, confirmed with two very positive OPK's and today I am 9 DPO. I started temping the other day however other cycles I've been more consecutive about doing so.  Yesterday I had a dramatic dip in my temp followed by a huge rise today of 99.3F  I was shocked by this and have never seen such a fluctuation. 
I took a test and it was negative,  but I guess I'm not out if I implanted yesterday....  Oh how I hope this is true.   When should I test again??
Any thoughts or opinions ladies?
