PLEASE HELP... Testing ? How soon can I test?


I am just wondering when I can test, how many days past ovulation? I just had a miscarriage about 5 weeks ago, I was only 7 weeks. So I have not had a cycle yet and don’t know if I am late yet or not, I just know it’s been about 5 weeks since I got 0 hcg on my lab work and the last 2 days I am having the same symptoms as when I was pregnant. Headaches everyday, bloated, gassy, breast tenderness as well. So I was wanting to test, I know the date of when we had sex that I could’ve conceive and I would be 10 dpo tomorrow. Please help, thank you!
