No period

So this hole month I haven't gotten my period but on the 22 & the 23 I had some bleed only in the morning for those today's & that's about it now we about to end with this month and I haven't gotten nothing but the thing is here my fiancé has a low count , can their still be a chance of pregnancy?? I've been having those symptoms like before a period comes but nothing has came & I do cramp here and their not all the time my boobs been sore the hole month my lower back hurt . So is their any clue or can someone give me advise ? I will really appreciate it .
