Warning Picture is (tmi). Hi fellow pregnant IVFers. I'm 7 weeks 5 days pregnant. We saw and heard the heartbeat at 6 weeks 4 days. I have been having brown spotting on and off since 5 weeks. I am on a waxy progesterone suppository once a night. This morning I woke up to a decent amount of brown cm/discharge on my liner. Is this normal? Is anyone else experiencing it? I have my next ultrasound on Monday and am just looking for some piece of mind before then. Thanks.
