I had been planning on a Mother's Day "announcement" for weeks, but it seems that I'll really only be out of the first trimester by Memorial weekend! At least that is still only a few weeks away. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150884 Mon, 07 May 2012 15:37:47 +0000 winniebee 150884@https://boards.hellobee.com/ <p>@mrsjyw: Risks substantially go down after 12 weeks....lookin good! </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150880 Mon, 07 May 2012 15:34:32 +0000 sulli301 150880@https://boards.hellobee.com/ <p>@highwire: I agree it's VERY confusing!! We are going to play it safe &amp; wait until 13.5 or 14 weeks to tell anyone (except for our parents who will will tell closer to 11 or 12 weeks). </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150551 Mon, 07 May 2012 12:30:26 +0000 mrsjyw 150551@https://boards.hellobee.com/ <p>I'm going to play it safe and believe that 1st trimester is over at 14w. I have my next dr's appt at 14w2d, so after that appt/us/heartbeat is when I'll FB announce.</p> <p>I did just pass the 12 w mark tho and do feel a bit better about m/c risks/etc. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150504 Mon, 07 May 2012 12:06:05 +0000 googly-eyes 150504@https://boards.hellobee.com/ <p>Just to be safe I considered it over when I hit 14w. Everyone counts it differently. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150460 Mon, 07 May 2012 11:26:43 +0000 winniebee 150460@https://boards.hellobee.com/ <p>So confusing! I just went by what my pregnancy apps told me, which was about 13 weeks and 3 days....</p> <p>I think it's 13 weeks and 3 days days - because if you divide 40/3 into three trimesters, you get 13.333333. So, second trimester starts at 13 weeks and 3 days, third trimester starts at 26 weeks, 6 days....I think? </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150449 Mon, 07 May 2012 11:19:06 +0000 MamaMoose 150449@https://boards.hellobee.com/ <p>I have found varying results but best I can tell it ends at the end of week 13 (3 13 week trimesters would give a totaly gestation of 39 weeks so that's as close as you are going to get to 3 equal parts). But as far as risk of miscarriage my doctor told me after 12 weeks she feels pretty confident that the risk is very minor. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150446 Mon, 07 May 2012 11:18:06 +0000 MsLipGloss 150446@https://boards.hellobee.com/ <p>Po-tay-to, Po-tah-to . . . I think the concensus is 13/14 weeks (although whether 13+1 = 14 or 14+0 = 14 depends on the counter). I considered myself in the 2nd trimester (as did my OB) at 13 weeks (13+0). </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150440 Mon, 07 May 2012 11:16:05 +0000 LuLu Mom 150440@https://boards.hellobee.com/ <p>My doctor considered the start of the 14th week to be the 2nd trimester. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150436 Mon, 07 May 2012 11:13:59 +0000 mamimami 150436@https://boards.hellobee.com/ <p>I think different people have different measures, but I consider 14 weeks (14 weeks, 0 days) to be the start of the 2nd tri. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150434 Mon, 07 May 2012 11:13:44 +0000 Running Elley 150434@https://boards.hellobee.com/ <p>Most of the things that I've seen say 13 weeks. </p> https://boards.hellobee.com/topic/when-is-the-first-trimester-over#post-150431 Mon, 07 May 2012 11:12:25 +0000 DillonLion 150431@https://boards.hellobee.com/ <p>Okay, seriously, I am confused. </p> <p>Is it 12 weeks? Is that 12 weeks, 1 day, or 12 weeks, 6 days? Or 13 weeks? Or 14? WHAT IS IT?! </p>
