I suppose with the stress of a possible UTI and weird spotting on Friday I am maybe looking for a problem when there hopefully isn't one, but I felt a lot of flutters at the end of 16w and pretty regularly in week 17. Now at the 18 w mark all is quiet. I am trying to get an apt tomorrow with my OB to follow up on the UTI issue so I'm going to bring it up then, but it just seems weird to me that the baby should be bigger but I'm feeling less. I did pull the Doppler out on Friday After my spotting episode and once more on Saturday to check and picked up the heartbeat, but my anxiety is getting the best of me. Can the baby face my back at this point or be turned in some way where there's less concentration of nerves?

The only thing I've got consistently right now are what feel like random pains for brief moments in my lower region under my bikini line, but they don't last long.
Re: How often did you feel flutters between 16-20 weeks?
Me 33, DH 37 -- TTC since Jan'12 -- Low AMH (0.78) & endo, SA w/ low motility
IUI's 1-3 = BFN, IVF converted to IUI 4/13 = BFN
IVF 1.2: 8R 6M 4F -- 2 blastocysts frozen, FET 8/15 = BFP!!
Beta #s = 445;1,098; 9,545 -- EDD 5/2 -- Team Pink!
I suggest reading the Mayo Guide to Pregnancy - it's a very fact based, not "worst case scenario" guide to pregnancy, including this kind of stuff. I suggest stepping away from What to Expect as it literally talks about every potential complication - it will drive you nuts! I wouldn't let DH read that.
That early, it's easy to go a few days or week without feeling anything as baby can move to a position where the kicks are going internally rather than those little butterfly kicks towards the belly.
Most OBs don't tell you to consider kick counts until around 25 weeks or so.
Off birth control March 2012 - Actively trying Sept 2012-April 2014
BFP on May 5th after Follistim & IUI #3
MC Sept '10, MC Dec '10, DS born 2012
Clomid + TI = BFP #1 March '13, MC April '13
Gonal F + trigger + IUI #1 = BFP #2 10/21/13, MC 10/31/13
Gonal F + trigger + IUI #2 = BFP #3 1/16/14, ectopic w/ heartbeat & rt salpingectomy 1/29/14
IVF #1 - ER 5/9/14 transfer cx'd due to high P4
FET #1 - 6/26/14 transferred 1 AA blast BFP!! Beta #1 13dp5dt - 1548 Beta #2 15dp5dt - 2748 Beta #3 18dp5dt - 7586
I've read lots of women don't feel much of anything until close to 25 weeks, so this really is very early to worry about irregular movement.
***Losses mentioned.*** TTC #1 since May 2012. Me: 37, OH: 41. Ectopic August 2012 => tubal damage.
