Hi, I was on the depo shot for a year, and my periods went real wacky, I didnt have one at all all while I was on the shot, and I didnt get one again until 4 months after I stopped taking it.
On the leaflet I got - to read before I decided to take that form of contraception- it mentioned, that it could take from 6 months till up to 2 years to become preg. After you stop taking the shot.
There is a chance she could be preg. But she wouldnt be very far along.
The depo shot is very affective.
You say her last shot was the month after u met her... And u have been together 5 months, which means her last shot was 4 months ago? The shot last for 3 months.. Which means she has only had the last 4 weeks to become preg. In.
At 4 weeks preg. Hcg levels are very low, meaning its quite likley to get a neg. Result even if u are preg.
At 4 weeks preg. Its very unlikley to have any symptons of being preg. Other than a missed period.
At 4 weeks preg. Your stomach will not have pooched out, you would have not felt any kicking- the fetus dosent have formed legs yet- its unlikley to have morning sickness, but your breasts could be quite tender- this is also a sign of getting your period though-.
I would give her another month, or, at least 2 more weeks before you get her to take another preg. Test. And dont hassle her, because girls dont like thinking that our men dont believe what we are telling them the first time round.
Hope this helps.
