Hey I have a few questions... Sorry it it's a little tmi... We're trying and I've never had a child before so I don't know it I'm having signs of pregnancy or not...

I got my iud out on the 4th of January and started my period right after 5-9. The dr told me to get an app so I did. My fertile days were the 16-21st. My other half and I had unprotected sex on 9,14,16,21,28 and for a little while I've felt tired,sick to stomach, dizzy, bloated/muscle pain in stomach, some smells make me sick to my stomach... Also I had spotting for 1-1.5 days very light and the app told me it could be something called implantation spotting and that occurred on 17-18. Can someone help me please I just don't know. Like is it to soon for a test??
