I want another baby

Katie. • 31 mother to two amazing boys, 8 and 3. I also have an amazing step daughter who is 19.
We are TTC but if it doesn't happen that's ok. I tried using apps to see when I was fertile. Idk if it was the peak of it or not. But my period is due in 2 days. I've been sick to my stomach on and off for a week now ... So tired... Backache... Headache... I'm hoping I'm pregnant!!! I've taken several tests last week which were all negative. Please send your baby dust vibes this way ?
