I went toilet for a wee and I had blood in my underwear and when I wiped. I had no pain so I didn't expect it. Can this be normal? I had private scan 2 weeks ago baby was fine etc. However I noticed my placenta being low and anterior. They really couldn't see much of baby on the 4d peek as placenta was in the way. Can someone tell me if this is normal or not? I've got cramps often all the way through and can't have sex or I spot.
