My period is very irregular and the last time i got it was December 5th of this year, and previous to that i got it sometime in August.Right now me and my Fiance are TTC. We had sex right after my period stopped and ever since then, until i started feeling kind of weird. I noticed that my boobs started to hurt, i started having constant diarrhea and constipation, feeling tired and sleepy all the time, chills, body-aches,fever, and frequent backaches. I didn't know what to make of it but sometimes you just know when something's not right. the symptoms didn't stop, instead they became more active. I can honestly say that I experienced all of the preg. syptoms including what is known as "implantation bleeding" which was very light and only last for a couple of days(my period is also very heavy but the bleeding i got was significantly lighter). the only thing i haven't experience yet is throwing up, but then again only 1 in 2 of all preg. women get this. I decided to take a home pregnancy test but it came out negative so this kinda made me lose hope, but then a friend of mines that already has a child said that all her other tests were negative too and that she didn't test positive until she was about 3 months. I also experienced some bleeding about 2 weeks ago for a couple of days(again lighter then my normal period) but then i read something on the internet that say some women do experience this during pregnancy. If i counted, by now i would be about 12 weeks along.I don't know what to do or think and even my stomach is starting to feel a little tighter then usual. should i wait a little longer and take a urine or blood test or just do it now and go with whatever result i get? PLS help.
