Ttc baby #2

Beth • I`m Beth and I just turned 30. Have a Beautiful 5 year old Daughter. TTC #2 for almost 3 years.
My periods are irregular but I been having dull period like cramps for 2 weeks and I have had headaches on and off and I'm super bloated my last test was on Thursday and BFN!!! So bummed but my back is killing me and I have been having insomnia. Broke out in same rash I had with my daughter. My period is due tomorrow was wandering if anyone else is experiencing this? My boobs feel fine but still don't know what to think. When should I test?
