Suggestions and Support

I have irregular cycles since my miscarriage almost a year ago. Took Chlomid in May, ovulated around day 21 of my cycle, did the dance with the hubs around that time a few times. I'm now 18 days past ovulation. Nausea, heartburn, gas, sore breasts, muscles in lower and stretching, fatigue, hubs says I'm a little more sensitive than usual.

Test or no? I don't want to jump the gun and get myself upset. We're not sure about next steps if it's neg. Not sure if my body can do another round of Chlomid. This would be my 4th, 2 live births, 1 miscarriage, and new baby?

Support appreciated
