So last night around 10 me and my family went on a Pokemon go and ice cream drive and decided to get Starbucks instead and I saw their new berry sparkling sangria tea so I was excited and said yes I want that so I drank a tall because I didn't know if I would like it 1 and 2 wasn't sure about it but anyways it was delicious I drank it super fast it was so freaking good omgee lol so we drove around ranking up our poke bags to collect more resources then finally started heading home around 11 and I went straight to bed I woke up at 2 with contractions and it made me go 💩 then tried to fall back asleep so at 4 got woken up with even worse contractions and 💩 and was thinking why is this...? is it because I just turned 38 weeks or was it that dang drink so I tried going back to sleep again succeeded 👏🏼 and woke up again at 6 with contractions again and made me sick to my stomach I felt like I needed to 💩 but had nothing left in me lmao 🙈 so I just sat up and did some breathing and rubbing my tummy.... I was so tired and I needed to sleep so I went back to sleep and now their a lot lighter they kind of feel like Braxton hicks... This was so weird. Was this a sign saying she is coming or what ?? I'm so confused lol
