just need advice

hiya, I just need a little advice, I suffered a miscarriage 6 months ago and have been ttc for the past couple of months but for the past few days I've woke up a few times in the night feeling like I'm going to be sick but haven't actually brought anything up, and I have also been having a weird feeling in my stomach it's like it did when I was pregnant before but I don't know what to think🙄
