Period during pregnancy?

I am always reading really ridiculous question on here, but i am wondering because about 3 weeks ago my boyfriend and i have unprotected sex PURPOSELY trying to have a kid. I have some pregnancy symptoms such as, sore boobs, being hungry, and tired. I've be pregnant before, but be young and have an abortion. My last time was June 12. Today is July 7, and I started cramping and have a very night light period, which is VERY unusual beside me. I am always have a heavy time and having to alteration tampons (gross i know). The cramping is what really confused me, because i had average cramps like i do beside every period. Well i also notice a brown color. I didn't take a pregnancy testing until today and it came out gloomy. I was going to dawdle to miss a period, but i guess i get it today? Could i still be pregnant? Because we are going to try again if im not.

Is there a road to get breasts firm again?

Hey, guess what? You can be pregnant. My first wife have 2 periods while preggo next to both our boys. So good luck on the preggo entity, and keep working on it. Just in suitcase.

Girls only! Do you expect this is normal?

Yes, it is possible you are pregnant. Within 3 weeks of trying, you might start to hold 'morning sickness' (throwing up) but, of course, this can begin anytime, not just within the Morning. Things such as crackers can help, and dry toast.
The bleeding you described is usually call 'Breakthrough Bleeding'. It could just be crude, or it is possible you could have miscarried (i know, it sounds stupid inside 4 wks, but it does happen sometimes.)
I have an idea that you should just linger, and maybe try again in a few weeks if you're not getting any more symptoms. Hope this help.. x
