Late period

Mo

We started <a href="https://glowing.com/glow-fertility-program">IVF</a> back in November. However I didn’t produce enough follicles so the doctor suggested we stop the cycle and try again in January. My period in December was a week early. And now for this month it is 10 days late. I keep taking pregnancy tests but they all come back negative. Has anyone else experienced this? I’m thinking the injections threw everything off :(
