Me and my partner been having sex for the last seven months and we've been using the same brand of condoms since but on the 18th of this month is broke and he ejaculated in me and didn't realize it broke until he was pull out after he was done and now I'm feeling completely confuse because I got off my period on the 16th before we had sex but ever since that had happen my body feel really different after a couple of days. I started feeling my waist is expanding and my lower back pain like when I was pregnant with my son  16 months ago and ive been feeling very tired and I've been feeling Nauseous and been having weird craving but I'm suppose to get my period in eight days <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> apps said. I also took a pregnant test yesterday but it was negative and I spoke to my doctor she said its to early to detect I will have to wait until my expected date for my period start if I'm late that would been I should buy a test and take it again
