Struggling 😥

Hey ladies!!!

So my husband and I have been ttc for about a year and a half and I know that is not very long BUT this would be his first and I have 2 girls from a previous relationship. They are 4 and 5 now. I got pregnant so fast with them that he is freaking out that he can’t have kids which would break his heart...My last period was April 1st through the 4th. We had sex 4 days in a row surrounding my ovulation day. I have had the past few days bloating, excessive gas, and SO much nausea that I have to stop what I’m doing to try and focus on not throwing up then it goes away. I’ve been tired all the time sleeping constantly and I did this with my first daughter. There are no other symptoms like breast tenderness yet anyways...I am 7 days before I’m supposed to start my period. I took a clear blue (not digital one) today around 330pm and it was negative...am I testing to early? Or am I just over thinking like I do every month. Thanks y’all!
