hi, me and my partner are trying for a baby. i have had multiple negative pregnancy tests over the last month or so, we have been trying for just under 3 months now, i have lower cramps, migraines everyday, going to the toilet more and in middle of the night but still no positive pregnancy test. what can i do to help get pregnant. and when taking a pregnancy test do i have to wait so long till all the sperm is out of my system or will it affect the tests? thank you.
