Pregnant?

We've been trying for 5 months and found out 3 months ago that my husband has low sperm. They wanted to go right to <a href="https://glowing.com/glow-fertility-program">IVF</a>. I found Fertilaid online and he started taking it a month ago. My period was 3 days late so I took a pregnancy test this morning and it's positive. Is this possible?  How accurate could it be? TIA.
