Can somebody help me out?

I haven't had my period in about 3-4 months and I'm irregular it comes and goes whenever it pleases, and I've taken bout 2 pregnancy tests monthly and all of them turned out negative. I'm already a mom of a one year old but I never felt like this before... my one friend said it could be from stress, my other said it might come even later cause I'm irregular, but the longest I've waited for it to come was 4 months. I don't trust going to walk ins cause I always believe they're wrong, my son was a few weeks old, I can't really remember cause it's been a while. but anyways, my son had the same problem as me when I was a baby except I had teterology of fellot and my son had a vsd repair, and I went to the walk in clinic before I went to the emerg. they said he was perfectly fine, because he was a month premy, they said his color is pale cause he's still developing and his finger nails were dark dark purple and blue because he's not fully developed, no other mothers had this problem. so I went to the emerg. and sure enough he needed surgery as well, so I don't ever want to step into a walk in clinic again.

The day I found out I was pregnant. I realized my period hasn't come after 6 months and after it said positive I was already 4 months. If what I'm asking doesn't make any sense feel free to correct me, I haven't slept all night and it's 8 am

Or am I just over reacting and getting impatient?
