So I'm very confused and im wondering if anyone else had this and what the out come was!?

So first off we are not trying to get pregnant right now but I've been having symptoms I have 2 kids already so I just know what it feels like. I do have irregular periods. But I had my normal period on Jan. 25th lasted 5 days. Then on the 5th day of ovulation I bleed again for about 4days. Last week I started feeling pregnancy symptoms so I tested i got like 3 or 4 faint tests showing positive. Followed by a negative. If I was according to the app I'd be around 3 weeks but I do know its early to get a positive test to. Well 2 days ago I started bleeding again and not a normal period bleeding either mine are normally heavy and with this one I could wear a light pad all day and it not be filled up thats how light it is. And now I'm showing negative tests. I called the doctor and she said it sounds like false positive tests. I had 8 faint positive and 5 negative the negative inbetween some of the positive except yesterday and today they are negative and there is alitle spotting still. Is this normal to have this many false positive testes? Has anyone else had this what was the outcome?

These are the faint positive the top you can see in person better than the picture

These are the negative ones

This is the faints with negative effect
