But I am still scared that AF is right around the corner. Friday I had an endometrial biopsy and blood work. Sunday I thought "what the heck" and took a hpt. My first ever BFP! DH and I were so excited. My ob called me Monday with b/w results. Thyroid is low...and serum pregnancy test was negative. Dr. said either test could be false or we did the serum too early. So far I have tested everyday (I know, DH and I are obsessed!) and they have all positive! So Monday I am going for a repeat serum test. We shall see how it all turns out soon enough! I am def. cautiously excited to be here!
