Help..?

I think I might be pregnant. I don't know though... About a month or so ago I took a test and it came back positive, but it was one of those early response tests, well then I went to go get professionally tested and they said it came back negative BUT since the test that I took came back positive, I still might need to worry because it was an early response one. Well I let it go and it hadn't crossed my mind much, I've had two periods since when so I was like whatever and told my mom I don't think I'm pregnant because I had my period, well THEN she proceeded to tell me that she had her period when she was pregnant with me and a few of my other siblings, so now I'm sitting here like fUUUUCK, and I've been rapidly gaining weight for the past few months, having to go to the bathroom so much, my emotions have been SO SO fucky, God I don't know what to do and I don't have the money to go buy another test so I don't know... Are there any home pregnancy tests that I can maybe try that anyone knows of? God I don't know... Just, help...
