Jenna
Im mentally losing my mind!!!!!!! Ok so heres the deal. I had pink spotting on Apr 30. I took a HPT may 1. It was a faint +. I went to dr the 4th and drew blood. Hcg level was 23. Four days later on the 8th i started bleeding so i went to the ER. Hcg was at 83. Was told to come back in 48 hrs to test again. Levels on the 10th were 45. Was told it was a MC. Called to follow up with OB and was told as long as im not going thru pads in an hour and the bleeding stops in a few days, no need to see the Dr. Bleeding stopped on the 12/13th and i never even semi filled a pad during the whole 5 days. So i saw the same pink spotting on this past Sat. So sunday i tested with an OPK. It was positive. I tested with a HPT. It was positive. So i bought a weeks predictor (pic). Went in for blood on sunday and my HCG was at 760. Was sent for an U/S today and the nurse tells me no proof of intrauterine pregnancy!!!!! Im planning on getting my Hcg taken again tomorrow. Wtf?!?!?!?! If i was misdiagnosed i should be far enough to see something. If i got pregnant again im prob just not far enough. Uuugggghhh i just want to know!!!!!! Either yes or no. If i did MC my numbers would not increase right????
