Pregnancy Info HOME

I'm 23 and my periods generally switch up on me a bit. I've been irregular off and on my whole life, generally at the begging of the month a few months and then randomly starting at the end of the month for a few months. My period are usually absolutely horrible, giving me cold sweats, making me dyzzie, causing excruciating pain, making me naeusious. I have been s_xually active for about a year and a half now, and had two s_xual partners, an ex and my current boyfriend. Well, I broke up with my ex around April and was not s_xually active from April to around the middle of July. I had my regular cycle in May, which was absolutely horrible, and then I completely missed my cycle in June. I started my cycle again around the 4th of July. About a week later I had s_x. In August I started right around a week late, around the 10th or 11. I ovulated around the 25, as I generally get a thick white discharge when I ovulate, so I can normally tell when I ovulate. I then had s_x around 2nd of August. My period is right at a week late at this point. I haven't experienced any signs of pregnancy, and have no va___al discharge, which is odd, as a few days before my period I generally have a light clear discharge. My question is, could the lack of signs and the lack of a discharge still leave room for pregnancy? I'm not exactly ready to have a baby, and the 2 times I've listed are the only 2 times I have unprotected s_x with my boyfriend, but I'm also worried that I might have low fertility, since my periods are so completely off and I've missed my period in June, only to have it start at 2 separate times in July and August.
