MAYBE I could be pregnant??

Cheyenne • ✨✨BABY DUST✨✨
Backstory; husband and I didn't want to get pregnant, so I was using Nexplanon, which is the implant in your arm. In November we decided to TTC, so I removed it. I haven't had a SINGLE PERIOD since before that time. I was also told it could take a year prior before I could even think about being excited to get pregnant, so we were okay with that, but would be happy nonetheless if we got a BFP prior to then. 
Currently; a week ago I was having major symptoms of conceived/period. Since I never had a period, I couldn't tell the difference if I was pregnant or not. I took several tests and all came up negative. Now I have had my FIRST period in over 8 months since the Nexplanon removal. HOWEVER; last week and the week prior my husband went at it with the sex. 
So now my question is...is there ANY WAY I could be pregnant? Regardless of the fact that I have a period now? Or is it just "oh, it's a period, NBD. Keep trying." Help??
