I have been pregnant a number of times, but have a history of recurrent miscarriages. I am currently 10 dpo. I used FRER. In the past, I have found FRER to turn positive and then go to the OB and find my HCG level in the single digits so I know it is very sensitive.
2 days ago, I started brown spotting. I have never had brown spotting except when pregnant. I am 40 so that is a long time to never have brown spotting except when pregnant (or at least not that I recall). I took the HPT that day and it came back with a very faint positive. I retook it later that same day, again, very faint positive. But then the next day, at 9 dpo, it was negative. Again today, at 10 dpo, this morning, it was very negative.
I did have a trigger shot which contains HCG. But I took an HPT at 6 dpo, which was 8 days post shot and it was negative so I really thought the 8 dpo test was accurate, but now I wonder if either this is a very early miscarriage, false negative, or if the 8 dpo tests picked up hcg from the shot that the test 2 days earlier did not pick up.
I will have blood work on Friday so I will know for sure by then. But I wanted to ask opinions because I am very confused over the brown spotting (I also do not recall having brown spotting with miscarriages either, but then, my period is not even due yet).
