Premature?

Amber
Hello ladies. A little bit about me, I am 27 year old and I just married my best friend of 7 years Feb 19. We have been wanting to have children for 5 years now, but was unable to because he had a vasectomy. We finally found a doctor that didn't want up to $10k for a surgery and had his reversal in December! Yay! He was supposed to take 3-4 weeks to heal. We may have started earlier out of excitement. 😌 (Fast forward) I keep track of my period on the other <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>, and it said that I was due Sunday to start. Well the week before that I was having horrible cramps which is not normal and broke out bad. I actually started bleeding Thursday and was so upset, and then Thursday night NOTHING! Friday I bled again and it lasted all day. Saturday I only bled a little in the morning. And I haven't bled since. I've taken pregnancy tests and they say negative but I am so hopeful that it's just to early to tell. Am I getting excited over nothing? Am I stressing myself out??
