I'm currently 7 months post partum and I haven't had a period in 4 months which before pregnancy I would only have like 3 to 4 periods a year yes I know this isn't normal but through the 4 months with no show from af I've taken test all negative but I'm so terrified I ovulated this month and we had an oopsy the other night so terrified I'm not ready to have another baby I had so many complications with my son I even almost died giving birth to him. I'm just not mentally or physically ready to be pregnant again... 🤦🏻‍♀️it's been almost two weeks from when we had a slip up! But if I am I'll be happy but I'm praying I'm not atleast not right now. So far I've been having a little back pain and ligament pain in my pelvic areas.... cramping! sore boobs...which was a sign with my son Nolan.and I've been craving pizza like a mf not saying that's a true sign but I guess time will tell. Oh and like two nights ago before I even mention it to my SO he layed his head on my stomach and I had asked him what he was doing.... he said "there's something in there I feel so drawn to your stomach" so yea I'm officially freaked the f**k out 💯🤦🏻‍♀️and also been having this weird feeling in my stomach fluttery kinda... idk tell me what you ladies think
