AM I CRAZY?

Sooo I’ve been feeling a little nauseous this morning , have been exhausted however I have no more pregnancy tests In the house.. I had my dear daughter this last June and I still have her heart beat music womb machine in the closet, so i decided to take it out and put it where it reads 8 weeks on my lower abdomen like i did when I was pregnant and I can HEAR A HEART BEAT... I think im losing my mind i have been feeling symptoms so i thought it was my period but nope, i haven’t had a period since September but i just thought I’ve always been irregular so couldn’t be anything abnormal but i’m going to be taking a test next week (to surprise hubby or maybe make him faint ) lol omg send help people people.

send help.
