I had a BFP on 20 Dec, 4 days before AF was due. Since then every test I've taken (8!) has been negative (except one BFP yesterday but it looked faulty). It has now been 2 weeks since the first BFN and still no AF or heavy bleed. I had light spotting at the time of the BFP but nothing much at all. Does everyone who has a chemical pregnancy have a heavy bleed? I have seen my doctor but he was fairly useless - just said to come back for a scan if AF doesn't come by end of month. I also have symptoms - bloating, constipation, indigestion, sensitive nipples, dizziness, and the last 3 days quite severe lower back pain. If anyone has been through anything similar, some advice would be much appreciated. Feeling a bit lost.
