Am i going crazy? Or am i just crazy?!?

So me and my husband are ttc baby#3

I've noticed that lately our 1&2 year olds have been acting strange these past few days. (Right now from my chart it says I'm 6dpo btw) but, my 2 year old practically never wanted anything to with me before and lately he's so clingy and wants me to hold him ALL THE TIME. He's constantly winning through out the day for any reason to get my attention & is constantly getting into everything he KNOWS he's not supposed to. At first I thought it was terrible two's.. but, it's definitely different considering he's almost three soon and he's always been easy. And he's my content baby. Always has been. And he definitely doesn't want his dad even when he comes home he runs for me lol (literally). Then my second son has always been a mommas boy but, he enjoys all the time he gets with Daddy. But, lately he'll come to me too when Dad gets home from work. Even when my husband is holding him he looks at me and makes that sad little face and silent cries with tears rolling down his cheeks. Like, he's overwhelmed with the feeling of not knowing if he wants to stay with his dad or just come to mommy and that's definitely a red flag for me. And now the BOTH of them have been looking underneath their legs. (Like that old wives tails) my mom believes them. Lol

I do have some symptoms and my husband definitely thinks I'm pregnant. Says I'm emotional and upset more often and I'm always asking for extra pickles on anything 😂😂 but I've always loved pickles.

I won't be able to test until Valentine's day. But basically what I'm wondering is. Has anyone experienced anything similar and found out they were actually pregnant?
