4 days late, 14 months of ttc

I’m 22 I have a 4 year old and trying for #2. It’s been 14 months since we started trying I thought it was going to be easy like in the movies. But recently since my last period I’ve had some episodes. So I ovulated 19 days ago and I’m 4days late for my period so my app says. I just started having some what regular periods again so I’m confused on if It’s just another weird period or I may be pregnant here’s why I think I am.

The other nice I brushed my teeth and to go to bed after awhile I just tasted blood.. wasn’t bleeding so it was the “copper” taste. Never had that with my first I only had bad morning sickness 🤷‍♀️ this happened randomly 3 times in between my days of dpo. I had 2 days in between where I was major cranky lol. Snapping at my bf and cranky with my bestfriend which has never happened in our years of friendship. I had a day where I just felt like a train of crying hit me and I just had to let it out laughed with my bf after because it felt so silly. I have very small cramps in my left cervix I think? For the last 4 days 🤷‍♀️ I keep testing everymorning and just nothing. Today I didn’t use a cheapy thinking it would be positive but no 😩 I noticed yesterday and today I just don’t have an appetite nothing sounds good, and on and off today I just feel a very like nausea like in the back of my throat. Idk but I’d like to hear what you have to say
