TTC after a chemical pregnancy

So I am new to this.... I am 30 years old and have been TTC for a little over a year! Turns out my husband had low sperm count( almost nothing) and was put on clomid to bring his count back up, it worked he now has a normal count YAY! Well in August I took a pregnancy test ( first response) and got a positive, so I was so excited and decided to take two more and they too came back positive! So the day before I was expecting AF i started spotting and continued like this for two days and got my cycle! I was so bummed 😔
