Is this positive?

I’m in need on some help! Long story short I went into pre term labor on Dec 20th at 14 weeks and we lost our precious baby. My hubby and I talked about trying again but since I haven’t had my period since September and it was irregular because of bc I don’t know when my fertile days are. We are trying to conceive again and I don’t want to stress but all I want is to feel the joy again of being pregnant again and have our rainbow baby.
