Hey, so found out 2 days ago that I was pregnant. Over the moon as me and DH have been trying for over 4 months now. However this morning when I went to the bathroom I realised I was having my 'period' this time it is very heavy and I'm very crampy (unusual) I did another pregnancy test this morning and it's a negative this must be a chemical pregnancy. This is the second time this has happened since we've been TTC. Is this anything to worry about?
