I've also had a lot of cramping this weekend. It's very much like period cramps. I've also had some spotting. I spoke to a midwife and she said that it can be both the movement of the uterus and the placenta taking over. She said with the spotting I should go in on Monday morning to the EPU as it's closed today and they should do a scan to check things out. I'm a little worried, but I can still find a strong heartbeat. Being able to find the hb has given me some reassurance, but a scan would make me feel better. Hopefully the scan will show that all is okay and what was causing the bleeding.
