Is this my period or IB Warning graphic Pics

Ana

I have irregular periods. My normal cycles are 31-40 days with 35 being the average. However randomly, I will go 70-79 days with a period (twice in the last 2.5 years).

This time around I am on CD 70 (last period was Dec 19, 2018), first time living with my boyfriend and have been using Pull Out method until more recently (I will say we started TTC last week of January).

I have taken a few pregnancy tests (last one was at the doctors on Wednesday)and they all came out negative. I started bleeding like this. Any insight?
