I had very slight spotting when AF was due then nothing. Couple of days later took pregnancy test and BFP indicator said 2-3 weeks. Due to spotting I went to get HCG levels checked as I've had MCs in the past. HCG levels aren't looking good - 84, 125, 179 every 2 days. I not have to wait until Saturday for next test. I've never had HCG this low even with my previous MCs. Im scared it's ectopic. Any experience out there?
