TTC and need to hear about symptoms!

Hi y'all!

I had the VSG on 4/5/17 and it's been the best decision of my life. I feel like myself again. I'm still heavier than I'd like to be but I'm healthier without a doubt.

My husband and I are planning to TTC but this past month we started not preventing and I'm now having some odd experiences. Wanted your thoughts or to see if anyone else has experienced this:

The first day of my last period was 2/11. Predicted ovulation date was 2/26 though based on signs, I think it was a few days later. Husband and I "didn't prevent" on 3/2. For the past week, I've had dark brown discharge and then today I had what looked like thicker mucus with some darker blood in it when I wiped. My lower back has also been hurting. Most noticeably, though, is that I ate food yesterday for lunch and within 3 minutes, I was in the bathroom rejecting it. I haven't done that since I first started solid foods with my surgery last year. I didn't eat too much...maybe too fast? Today, I just ate a little soup and I feel so full and queasy. My heartburn has been very bad too.

My question is, did you all have symptoms like that full feeling we all got right after surgery that looking back were pregnancy signs?
