Period lasting longer...(Hoping for some answers....)

So my period started last Sunday morning, around 2-3am (7/15). It was light all week, which is weird because it usually gets heavier around the 3rd or 4th day then gets light again. What threw me off was that there were no clots either. (Again, not normal for me). Saturday, I was able to go a couple hours without a tampon in and then I started bleeding lightly again. Sunday, I was able to go the whole day without. Then my fiancé and I BD, and after he asked me if I was bleeding. I thought I was off!! He was a mess!! My periods last a full week, the last day I’m light normally. Well, I’ve had to wear a regular tampon yesterday and today. I would go to the doctor, but right now I don’t have insurance or enough $$ to go, I hate being poor!!! I’m posting all this to see if maybe anyone has gone through this too and if there are any answers? Before anyone says that I need to go to the gyno, please understand that I would if I could. It’s just not in the funds right now. We’re living paycheck to paycheck trying to keep the roof over our heads and to keep our son fed. I’m just confused!! (We have been trying for baby #2 for 3 years if that helps any) Thank you
