advice.

This is the first time I have ever posted anything. 

I'm really scared, I have had a lot of health problems over the past 18 months. I was diagnosed with stage 4 Endometriosis June 2016. I have had 3 separate extensive surgeries since and on top of that I got split from my husband Feb 2016 and the divorce came through July 2016. So it's been very stressful. I have a little boy also he's 2 and a half. 

Basically after my last surgery (5th April 2017) which was emergency surgery to remove my appendix, a cyst the size of an orange from my right ovary and they did another laparoscopy and found that since my last extensive surgery in October even though I had a coil fitted the coil hasn't worked and the endometriosis has grown back. When I was discharged I was told given everything. That's happened if I wanted another baby this was my last opportunity to try as the only option left is a hysterectomy. 

I met and fell in love with my boyfriend last May, never expected it to happen. Was the last thing in the world I wanted and was looking for but we've been together since and he's wonderful he really is. We discussed what the surgeon had said to me and I had my coil taken out on 8th April to let nature take its course and if I did conceive it wouldn't be the end of the world for us and everything would fit together as it just has so far for us. 

He told me on Monday that he's changed his mind and doesn't want kids. 

That's absolutely fine I'm just glad he told me etc no problem at all, however this is where I need help, resassurance and just need to get it off my chest. 

On Monday I was 8 DPO I only know that because I was having really strange cramps all day which even with Endo is a weird different kind of pain it was dead centre in my stomach. My boyf also noticed last week my boobs look bigger, I have been extremely dizzy and tired and over the last 2 days I have felt a bit quesy at night. 

I know no one can give me definite answers but I'm not sure what to do, I'm scared it was implantation cramp I had, I'm scared i'm going to loose him, I'm scared and just a bit lonely that's all. Is it possible to get pregnant so quickly after the coil? I have done nothing but read online since Monday. Please help x
