Intitially if my levels hadnt gone from 54 to 56 on 14DPO and 16DPO I wouldnt be too worried. But my levels are very low anyway for how many DPO I am. According to the Betabase 18DPO levels should be over or around 400. Also I have been reseraching others levels and I havnt found any levels this low that have been viable ion other pregnancy's. My levels are preety much doing the exact same thing as last time I had my ectopic, very low and unpredicable. I also have right sided pain. The only other time I have been PG was my last ectoic and it just feels exactly the same. Last time it hurt when I went to th toilet (pushed - sorry TMI) and it is the same again.
