Not sure how to topic this one.

I am 29 and we have a 2 year old daughter. We conceived our daughter after 6 rounds of Clomid failed, 2 rounds of femara, 2 rounds of insemination, and then luckily had success our first round of IVF. I then got on birth control just in case there was that chance I could get pregnant after having our daughter and stayed on it just to keep track of my periods better. I finally decided to stop taking the pill this month. I am due to start my period and have no symptoms at all. No bloating, no acne, no back pain, and those were all things I have experienced previously. I would be happy if somehow I end up pregnant but wanted to see who had an opinion on this. When do I test?
