Im 13 weeks today some apps say im in my second trimester and others still say first.... which is it?

@babymamamoore, yea it’s a app But for some reason it’s not showing up when I search for it now
@jerseymomx2 that screenshot you sent, is it from a pregnancy app? If so, which one? Anyone have good recommendations for pregnancy apps that have a lot of info?
I say 13 for second and 27 for third. Either way, one week doesn’t make much of a difference- except between weeks 23/24
@jesuslover82 in the books that the doc gave me it says 13 too... thanks love
Update: Im having real contractions and currectly on an IV. Nurse says im dehydrated keep me in prayer ladies
Im feeling fake vibes from a new person but I'm not saying anything. I'll just wait and see. I could be wrong but you know 🤷♀
So im going to delete my page at midnight I'm over this app I just wanna say bye to my girl's im going to miss y'all
So im 23 weeks and everyone says i just turned 5 months. Im not sure how to tell what month im in.
