Pregnancy after miscarriage

Emma • A miscarriage pcos no periods for years. No guides. Advised no babies naturally due to issues then this little miracle
I need some advice please. I suffered with a miscarriage four weeks ago. Had awful surgery. As I was getting over it I took an ovulation test 21st April which was very positive. We have been using protection bar one time. We took 1 1/2 yrs to fall pregnant as I have PCOS. Now there is no period but I'm feeling tired, grumpy, sore, hormonal, hungry etc. I took a test but I think it's too early yet. Do you think that I could be? I'm worried that we will have to wait as we plan to actively try again from tomorrow. Any advice would be welcome. Thank you x
