TTC-Post IUD

Hi! I got my IUD out on Monday. This might be a dumb question and I’m aware of that but a lot of you know way more than me! My ovulation window was supposed to start today. I have been taking ovulation tests just in case. But since I had an IUD with hormones in it, it’s normal for ovulation to take a bit to kick back into gear. So my questions are these:

1. Is it possible to become pregnant if my ovulation tests are lighter than the control line (I use the pregmate ones)?

2. Has this happened to anyone?

3. Are there things I can do to help get my ovulation back on track.

Thanks ❤️
