Hi – As far as your question goes, I know a few people that never had symptoms until they were about 12 to 14 weeks! I may not be much help but, being that I’ve been down that road three times but, not successfully finished I can give you some info. The first time I didn’t even know I was because I never had a sign the first, at least I thought, but my boyfriend said I was going to the bathroom alot more than usual and he could see my stomach move and hear things. I’m sure my rambling doesn’t help but short version, it’s possible!
Hope this helps you some>
