Late period or possible pregnancy ??

So I am on CD 35. This is my first cycle since I got my iud taken out in early November, started my period two days later. I got my iud out because my husband and I are TTC for baby #2.

My period this month was my first since before I found out I was pregnant in 2020, had my daughter in October, iud put in on Jan 2021.

I was taking OKP tests and I ovulated late. My period was supposed to start Friday and so it’s almost two days late. I have taken 3 tests so far before tonight, one a few days I was supposed to start, one Friday morning and one this morning. All negative. I took one just a little while ago and I don’t know if I have line eyes or it’s an indent or the start of a second line. I do plan on taking another test in the AM of course.

My nipples have been more sensitive, I’ve been bloated, some slight cramps. I have been feeling nauseous at night for the past two nights. It came on about the same time as the night before. And yesterday it went away pretty quick, no I didn’t get sick, but tonight it’s just hanging around. I feel fine besides that so I’m pretty sure I’m not sick. I’ve eaten the same things my husband and daughter have eaten today so it’s not the food.

I’m hoping that I don’t just have line eyes and that’s it’s not just an indent. I have had miscarriage before, a chemical pregnancy, and took a year to get pregnant with my daughter, so while I know it doesn’t always happen the first time you try I’m hoping for the best 🤞🏻
