LONG POST ALERT!!

So this is gonna be kinda long and maybe a little confusing but I just need to put it out there because I’m just feeling a little anxious and nervous. SO...I used to get my period every month around the same time very regular and very heavy. Then I went on BC (nexplanon). I had one very heavy period that lasted nine days and then nothing for almost two years. Due to some pain in my arm I got it removed end of July 2016. I didn’t get my first period until 9 months later in April 2017. I got it April, may, June. Then nothing that July. Then I had some spotting/ light bleeding for a few days in the beginning of August. BUT THEN... nothing after that so I finally decided to go see my gynecologist. She prescribed provera and I took it for ten day beginning of December and got my “withdrawal” bleed December 18th and it was light at first then heavy. Lasted until December 26th. Then glow said I ovulated on the 1st of January. So during my fertile window and on ovulation day me and my fiancé baby danced. I don’t know if or when I actually ovulated because my doctor said that even though I had a withdrawal bleed it doesn’t mean I’ll actually ovulate. ANYWAY.. I guess I’m just confused and nervous because I really wanna be pregnant and I’ve been trying everything I can. I was suppose to start my next period on the 15th this month according to glow but I haven’t yet. I have been feeling little twinges in both my right and left side off and on. I’ve started to get slight nausea at times and very sensitive to smells. Really bad headaches out of no where. a lot of extra discharge. And I’ve noticed my nipples are sore and my areolas are a bit darker in color and very noticeable blue veins.Extremely tired all the time very unmotivated just wanna sleep. But then slight insomnia at night sometimes. On and off constipation and diarrhea. Idk if anyone can help me understand what’s going on. I wanna test but I’m too scared of a BFN so I’m trying to wait until end of the month...any advice?
